I have a script that effectively does the following:
top_script.py:
os.system("bash_script.sh")
bash_script.sh
python3 child_script.py
child_script.py
# Actual work goes here
In VSCode, I love the integrated debugger, but when I follow their advice[1] when launching from the IDE, I get "ECONNREFUSED 127.0.0.1:5678".
When I execute the following from the integrated terminal in VSCode, it runs without the errors, but it doesn't stop on breakpoints in child_script.py.
python3 -m debugpy --listen 5678 top_script.py
How can I execute the top script first (either from the IDE or command line) and have breakpoints I attach in child_script.py be rendered in VSCode?

It's fairly simple. You can add a configuration to your launch.json file like the following:
{
"name": "MySubProcess",
"type": "python",
"request": "attach",
"processId": "${command:pickProcess}
}
Now start your python process separately (via a prompt, or however). This will generate a python subprocess. You can see this in Windows Task Manager (or also in MacOS Activity monitor, or in Linux a similar way).
In VSCode, then click Debug, (select your subprocess configuration: "MySubProcess" in our example above), and then choose the process which was just started. The debugger will then stop at the breakpoints in your subprocess code.
The problem is that by using os.system() the debugger doesn't know you started another Python interpreter that you care about. What you will need to do is attach to the second process. Details will vary depending on how you want to set this up, but you can look at https://code.visualstudio.com/docs/python/debugging#_local-script-debugging as a starting point.
I followed RexBarker's suggestion, but VSC always gave me an error of "Timed out waiting for debug server to connect". In order to find out the cause, the "log to file" was enabled in the Configuration like below,
{
"name": "MySubProcess",
"type": "python",
"request": "attach",
"processId": "${command:pickProcess}",
"logToFile": true
}
Then I could find the detailed error in the log file on the VSC host, which is located at ~/.local/share/code-server/extensions/ms-python.python-2021.5.926500501/debugpy.adapter-{pid}.log
It told me 'gdb' not found. After I installed gdb, it works as expected.
I have just installed VS Code and the Python extension, and I have not been able to get the debugger to work. Every time I try to use the debugger, it just skips over any breakpoints that I have set and runs the program like normal.
I am using VS Code on a Windows 10 PC with Python 3.7.3 and the Python extension installed. I followed the instructions here (https://code.visualstudio.com/docs/python/python-tutorial) to make a test folder called 'hello' in C:\python_work\hello and create a program called 'hello.py' inside that folder. hello.py is shown below. I tried using the debugger both by pressing the green arrow and by pressing F5, but neither seemed to make the debugger work properly. My 'launch.json' file is also shown below.
hello.py:
msg = "Hello World!"
print(msg) # Breakpoint
launch.json:
{
// Use IntelliSense to learn about possible attributes.

"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"stopOnEntry": true
},
]
}
I expected the bottom bar to turn orange and the program to stop on the second line, allowing me to examine the local and global variables in the preview pane. Instead, the bottom bar stayed orange for 1/2 a second while the program ran as if I had pressed "Run Python File in Terminal," without stopping at the breakpoint. Please help!
Setting "justMyCode": false makes it stop at breakpoint:
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Debug Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"stopOnEntry": true,
"justMyCode": false
},
]
}
If you're using a pytest-cov module you might also wanna have a look at pytest configuration settings note:
Note If you have the pytest-cov coverage module installed, VS Code doesn't stop at breakpoints while debugging because pytest-cov is using the same technique to access the source code being run. To prevent this behavior, include --no-cov in pytestArgs when debugging tests, for example by adding "env": {"PYTEST_ADDOPTS": "--no-cov"} to your debug configuration.
See an example configuration file (launch.json) below:
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Tests",
"type": "python",
"request": "test",
"console": "integratedTerminal",
"justMyCode": false,
"env": {"PYTEST_ADDOPTS": "--no-cov"}
}
]
}
I experienced the same behaviour and was able to solve it by installing the virtual environment of Python in the following way:
[MyProjectFolder] \ venv
by entering the command
python -m venv [MyProjectFolder]\venv
in the console.
VS Code seems to expect exactly that folder structure.
Before I had installed the venv-folder-structure directly in my projects-folder, i.e.
[MyProjectFolder] \ Scripts
[MyProjectFolder] \ Lib
[MyProjectFolder] \ Include
[MyProjectFolder] \ pyvenv.cfg
which did not work and caused exactly the described debug problems.
just as a reference: VS Code version 1.52.1 and Python 3.8.5
Downgrading from Python 3.9 to 3.8 worked for me.
VC Code 1.56.2 ignored breakpoints running Python 3.9 64-bit on Windows 10 version 20H2. Installing Python 3.8.10 64-bit fixed the problem. I just needed to select the Python 3.8.10 interpreter within VS code and it now recognizes breakpoints. No changes to the configuration file were needed, for example, I did not need "justMyCode": false
I realize this is an old question, but my google search lead me to it. Many of the previous answers no longer apply. So I'm posting this fix for others who land here in 2021 trying to use 3.9.
I had the same problem having upgraded from Python version 3.7 to version 3.9. I later found out that the old version was 32 bit, and the new version I upgraded to was 64 bit, which apparently caused the issues. Uninstalling the 64 bit version and installing the 32 bit version of Python 3.9 solved my problem, and I was then able to use the Visual Studio Code breakpoint functionality again.
For everyone coming here looking for a solution related to breakpoints in python unittests:
If not already done add a configuration file, i.e. launch.json, as described in the vscode python debugging tutorial.
For me the following configuration settings worked, whereby setting cwd (because of src and test folders) and purpose (see also here) were essential.
"version": "0.2.0",
"configurations": [
{
"name": "Python: Test Cases",
"type": "python",
"request": "launch",
"cwd": "${workspaceFolder}/afinad/src",
"purpose": [
"debug-test"
],
"console": "integratedTerminal",
}
]
Happy debugging!
I recently found out ( 5th May 2020) that using Python 3.9 as interpreter the breakpoints were not hitting. Install 3.8 and it will start working again.
My issue was that I was putting the breakpoint on the line of the function declaration itself, so the def foo(x): line, instead of putting the breakpoint on the first non-comment line inside of the function.
If the first line of your function is a comment, the debugger will assume you meant to place the breakpoint on the line of the function declaration and move your breakpoint back, so really make sure you aren't placing your breakpoint on a comment!
Another source of no-breakpoints-working is elevate:
try: # https://pypi.org/project/elevate/
from elevate import elevate
except ModuleNotFoundError: # install it if not found
subprocess.call([sys.executable, "-m", "pip", "install", 'elevate'])
finally:
from elevate import elevate
# require elevated permissions right away...
elevate()
The elevate() command restarts the program as a new (child) process, so the entire file becomes un-breakpoint-able. From the author:
On Windows, the new process’s standard streams are not attached to the parent, which is an inherent limitation of UAC.
In windows, to debug python applications in VS Code which need to be run as administrator, a work-around is this:
Close VS Code.
Right-click VS Code icon, choose "Run as Administrator."
Linux users could likely do the same with sudo code. Now the process will be spawned initially as administrator, so the call to elevate() does nothing and the whole file is debuggable.
Another source of debugger not stopping at breakpoint: an homonym file, from another directory, is open in VS Code.
In fact, VS Code can set breakpoints on any Python file, even outside of your Python project's directory; if the path of the file does not match the one in launch.json, "program": [your-file-name-here] entry, then breakpoints are not hit.
For example: copies of Python source files are located under dist/lib, the output of setuptools (run: python setup.py bdist_wheel to generate them).
If dist/lib is not excluded through .gitignore, then its contents shows up in the search results sidebar and can be click open by mistake.
Caveat: the above does not hold if the launch.json configuration has "program": "${file}".
I (re)downloaded VS Code again: https://code.visualstudio.com/
The breakpoint got to show up on hover and function with the Run and Debug for the python file I was working on.
Additionally, I had to solve a syntax error in my code before the debugger buttons (step over/in, etc) had to go through the code lines
I have been battling with this for the last hour, and it finally worked by renaming my python file from camelCase.py to snake_case.py
Visual Studio Code was recently released and I liked the look of it and the features it offered, so I figured I would give it a go.
I downloaded the application from the downloads page, fired it up, messed around a bit with some of the features ... and then realized I had no idea how to actually execute any of my Python code!
I really like the look and feel/usability/features of Visual Studio Code, but I can't seem to find out how to run my Python code, a real killer because that's what I program primarily in.
Is there is a way to execute Python code in Visual Studio Code?
There is a much easier way to run Python, and it doesn't need any configuration:
Install the Code Runner Extension.
Open the Python code file in Text Editor.
To run Python code:
use shortcut Ctrl + Alt + N
or press F1 and then select/type Run Code,
or right click the Text Editor and then click Run Code in the editor context menu
or click the Run Code button in the editor title menu
or click Run Code button in the context menu of file explorer
To stop the running code:
use shortcut Ctrl + Alt + M
or press F1 and then select/type Stop Code Run
or right click the Output Channel and then click Stop Code Run in the context menu
If you want to add the Python path, you could go to File → Preference → Settings, and add the Python path like below:
"code-runner.executorMap":
{
"python": "\"C:\\Program Files\\Python35\\python.exe\" -u"
}
In case you have installed the Python extension and manually set your interpreter already, you could configure your settings.json file as follows:
{
"python.pythonPath": "C:\\\\python36\\\\python36.exe",
"code-runner.executorMap":
{
"python": "$pythonPath -u $fullFileName"
}
}
Here is how to configure Task Runner in Visual Studio Code to run a .py file.
In your console, press Ctrl + Shift + P (Windows) or Cmd + Shift + P (Apple). This brings up a search box where you search for "Configure Task Runner"
If this is the first time you open the "Task: Configure Task Runner", you need to select "other" at the bottom of the next selection list.
This will bring up the properties which you can then change to suit your preference. In this case you want to change the following properties;
Change the Command property from "tsc" (TypeScript) to "Python"
Change showOutput from "silent" to "Always"
Change args (Arguments) from ["Helloworld.ts"] to ["${file}"] (filename)
Delete the last property problemMatcher
Save the changes made
You can now open your .py file and run it nicely with the shortcut Ctrl + Shift + B (Windows) or Cmd + Shift + B (Apple).
All these answers are obsolete now.
Currently you have to:
install the Python language extension (and Python, obviously)
open folder (important!), open any Python file inside that folder
switch to debug "tab"(?) and click on the gearbox (with hint 'Configure of Fix 'launch.json'')
save the opened launch.json file (it's placed in .vscode subdirectory in the folder opened in step #2)
finally, click the green triangle or hit F5
No additional extensions or manual launch.json editing is required now.
You can add a custom task to do this. Here is a basic custom task for Python.
{
"version": "0.1.0",
"command": "c:\\Python34\\python",
"args": ["app.py"],
"problemMatcher": {
"fileLocation": ["relative", "${workspaceRoot}"],
"pattern": {
"regexp": "^(.*)+s$",
"message": 1
}
}
}
You add this to file tasks.json and press Ctrl + Shift + B to run it.
To extend vlad2135's answer (read his first); that is how you set up Python debugging in Visual Studio Code with Don Jayamanne's great Python extension (which is a pretty full featured IDE for Python these days, and arguably one of Visual Studio Code's best language extensions, IMO).
Basically, when you click the gear icon, it creates a launch.json file in your .vscode directory in your workspace. You can also make this yourself, but it's probably just simpler to let Visual Studio Code do the heavy lifting. Here's an example file:
You'll notice something cool after you generate it. It automatically created a bunch of configurations (most of mine are cut off; just scroll to see them all) with different settings and extra features for different libraries or environments (like Django).
The one you'll probably end up using the most is Python; which is a plain (in my case C)Python debugger and is easiest to work with settings wise.
I'll make a short walkthrough of the JSON attributes for this one, since the others use the pretty much same configuration with only different interpreter paths and one or two different other features there.
name: The name of the configuration. A useful example of why you would change it is if you have two Python configurations which use the same type of config, but different arguments. It's what shows up in the box you see on the top left (my box says "python" since I'm using the default Python configuration).
type: Interpreter type. You generally don't want to change this one.
request: How you want to run your code, and you generally don't want to change this one either. Default value is "launch", but changing it to "attach" allows the debugger to attach to an already running Python process. Instead of changing it, add a configuration of type attach and use that.
stopOnEntry: Python debuggers like to have an invisible break-point when you start the program so you can see the entry-point file and where your first line of active code is. It drives some C#/Java programmers like me insane. false if you don't want it, true otherwise.
pythonPath: The path to your install of Python. The default value gets the extension level default in the user/workspace settings. Change it here if you want to have different Pythons for different debug processes. Change it in workspace settings if you want to change it for all debug processes set to the default configuration in a project. Change it in user setting to change where the extension finds Pythons across all projects. (4/12/2017 The following was fixed in extension version 0.6.1). Ironically enough, this gets auto-generated wrong. It auto-generates to "${config.python.pythonPath}" which is deprecated in the newer Visual Studio Code versions. It might still work, but you should use "${config:python.pythonPath}" instead for your default first python on your path or Visual Studio Code settings. (4/6/2017 Edit: This should be fixed in the next release. The team committed the fix a few days ago.)
program: The initial file that you debugger starts up when you hit run. "${workspaceRoot}" is the root folder you opened up as your workspace (When you go over to the file icon, the base open folder). Another neat trick if you want to get your program running quickly, or you have multiple entry points to your program is to set this to "${file}" which will start debugging at the file you have open and in focus in the moment you hit debug.
cwd: The current working directory folder of the project you're running. Usually you'll just want to leave this "${workspaceRoot}".
debugOptions: Some debugger flags. The ones in the picture are default flags, you can find more flags in the python debugger pages, I'm sure.
args: This isn't actually a default configuration setting, but a useful one nonetheless (and probably what the OP was asking about). These are the command line arguments that you pass in to your program. The debugger passes these in as though they you had typed: python file.py [args] into your terminal; passing each JSON string in the list to the program in order.
You can go here for more information on the Visual Studio Code file variables you can use to configure your debuggers and paths.
You can go here for the extension's own documentation on launch options, with both optional and required attributes.
You can click the Add Configuration button at the bottom right if you don't see the config template already in the file. It'll give you a list to auto generate a configuration for most of the common debug processes out there.
Now, as per vlad's answer, you may add any breakpoints you need as per normal visual debuggers, choose which run configuration you want in the top left dropdown menu and you can tap the green arrow to the left to the configuration name to start your program.
Pro tip: Different people on your team use different IDEs and they probably don't need your configuration files. Visual Studio Code nearly always puts it's IDE files in one place (by design for this purpose; I assume), launch or otherwise so make sure to add directory .vscode/ to your .gitignore if this is your first time generating a Visual Studio Code file (this process will create the folder in your workspace if you don't have it already)!
There is a Run Python File in Terminal command available in the Python for Visual Studio Code extension.
As stated in Visual Studio Code documentation, just right-click anywhere in the editor and select Run Python File in Terminal.
Install the Python extension (Python should be installed in your system). To install the Python Extension, press Ctrl + Shift + X and then type 'python' and enter. Install the extension.
Open the file containing Python code. Yes! A .py file.
Now to run the .py code, simply right click on the editor screen and hit 'Run Python File in the Terminal'. That's it!
Now this is the additional step. Actually I got irritated by clicking again and again, so I set up the keyboard shortcut.
Hit that Settings-type-looking-like icon on bottom-left side → Keyboard Shortcuts → type 'Run Python File in the Terminal'. Now you will see that + sign, go choose your shortcut. You're done!
So there are four ways to run Python in Visual Studio Code so far:
Via an integrated terminal (come on, it's integrated! So technically you run it from within Visual Studio Code ;)
No need to install any extension.
No need to create and configure anything (assuming that you already have python in your $PATH).
⌃Space (open terminal) and python my_file.py (run file).
Via custom Task (accepted Fenton's answer):
No need to install any extension.
Default Visual Studio Code's way of doing things.
Beware not to copy-paste the answer because its problemMatcher.pattern.regexp is broken and it hangs the editor. It's better to either delete problemMatcher or change the regexp to at least ^\\s+(.*)$.
Via Code Runner extension (#JanHan's answer):
Need to configure code-runner.executorMap in User Settings (add path to your python).
Very helpful extension especially if you run not only Python in Visual Studio Code.
Via Microsoft's official Python extension (vlad2135's answer):
Need to create launch.js (a couple of clicks in Visual Studio Code's Debug tab).
The extension is a must-have for those who wants to use Visual Studio Code as a primary IDE for Python.
There is a lot of confusion around Visual Studio Code tasks and the debugger. Let's discuss about it first so that we understand when to use tasks and when to use the debugger.
Tasks
The official documentation says -
Lots of tools exist to automate tasks like linting, building,
packaging, testing, or deploying software systems. Examples include
the TypeScript Compiler, linters like ESLint and TSLint as well as
build systems like Make, Ant, Gulp, Jake, Rake, and MSBuild.
.... Tasks in VS Code can be configured to run scripts and start
processes so that many of these existing tools can be used from within
VS Code without having to enter a command line or write new code.
So, tasks are not for debugging, compiling or executing our programs.
Debugger
If we check the debugger documentation, we will find there is something called run mode. It says -
In addition to debugging a program, VS Code supports running the
program. The Debug: Start Without Debugging action is triggered with
Ctrl+F5 and uses the currently selected launch configuration. Many of
the launch configuration attributes are supported in 'Run' mode. VS
Code maintains a debug session while the program is running, and
pressing the Stop button terminates the program.
So, press F5 and Visual Studio Code will try to debug your currently active file.
Press Ctrl + F5 and Visual Studio Code will ignore your breakpoints and run the code.
Configuring the debugger
To configure the debugger, go through the documentation. In summary it says, you should modify the launch.json file. For starters, to run the code in integrated terminal (inside Visual Studio Code), use -
{
"name": "Python: Current File (Integrated Terminal)",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal"
}
To run the code in an external terminal (outside of Visual Studio Code), use -
{
"name": "Python: Current File (External Terminal)",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "externalTerminal"
}
N.B. If all documentation was easy to search and understand then we probably would not need Stack Overflow. Fortunately, the documentation I mentioned in this post is really easy to understand. Please feel free to read, ponder and enjoy.
In the latest version (1.36) of Visual Studio Code (Python):
Press F5 and then hit Enter to run your code in the integrated terminal.
Ctrl + A and then hit Shift + Enter to run your code in the interactive IPython shell.
You no longer need any additional extensions. You can simply switch the output of the debugger to the integrated terminal.
Ctrl+Shift+D, then select Integrated Terminal/Console from the dropdown at the top.
If I just want to run the Python file in the terminal, I'll make a keyboard shortcut for the command because there isn't one by default (you need to have the Python interpreter executable in your path):
Go to Preferences (the gear icon on the bottom left) → Keyboard Shortcuts
Type 'run Python file in terminal'
Click on the '+' for that command and enter your keyboard shortcut
I use Ctrl + Alt + N.
If you are using the latest version of Visual Studio Code (version 1.21.1). The task.json format has changed, see here. So the answer by Fenton and by python_starter may no longer be valid.
Before starting configuration
Before you start configuring Visual Studio Code for running your Python file.
Make sure that you have installed Python and added its executable to your system PATH.
You must set the folder where your python source file resides as your working folder (go to File -> Open Folder to set your working folder).
Configuration steps
Now you can configure the task. The following steps will help you run your python file correctly:
use Ctrl+Shift+P and input task, you will see a list of options, select Tasks: Configure Task.
You will then be prompted create task.json from template, choose this option, and you will be prompted to choose from a list of options. Choose Others.
Then in the opened task.json file, use the following settings:
{
"version": "2.0.0",
"tasks": [
{
"label": "run this script",
"type": "shell",
"command": "python",
"args": [
"${file}"
],
"problemMatcher": []
}
]
}
In the above settings, you can give a meaningful label to this task. For example, run python.
Go to the Tasks menu and click Run Task. You will be prompted to choose the task. Just choose the newly created run this script task. You will see the result in the TERMINAL tab.
For a more complete tutorial about task configuration, go to the Visual Studio Code official documentation.
Here's the current (September 2018) extensions for running Python code:
Official Python extension: This is a must install.
Code Runner: Incredibly useful for all sorts of languages, not just Python. I would highly recommend installing.
AREPL: Real-time Python scratchpad that displays your variables in a side window. I'm the creator of this, so obviously I think it's great, but I can't give a unbiased opinion ¯\(ツ)/¯
Wolf: Real-time Python scratchpad that displays results inline
And of course if you use the integrated terminal you can run Python code in there and not have to install any extensions.
Super simple:
Press the F5 key and the code will run.
If a breakpoint is set, pressing F5 will stop at the breakpoint and run the code in debug mode.
Other Method - To add Shortcut
Note: You must have Python Extension By Microsoft installed in Visual Studio Code, and the Python interpreter selected in the lower-left corner.
Go to File → Preferences → Keyboard Shortcuts (alternatively, you can press Ctrl + K + S)
In the search box, enter python.execInTerminal
Double click that result (alternatively, you can click the plus icon)
Press Ctrl + Alt + B to register this as the keybinding (alternatively, you can enter your own keybinding)
Now you can close the Keyboard Shortcuts tab
Go to the Python file you want to run and press Ctrl + Alt + B (alternatively, you can press the keybinding you set) to run it. The output will be shown in the bottom terminal tab.
in new Version of VSCode (2019 and newer) We have run and debug Button for python,
Debug :F5
Run without Debug :Ctrl + F5
So you can change it by go to File > Preferences > Keyboard Shortcuts
search for RUN: start Without Debugging and change Shortcut to what you want.
its so easy and work for Me (my VSCode Version is 1.51 but new update is available).
Note: You must have Python Extension By Microsoft installed in Visual Studio Code, and the Python interpreter selected in the lower-left corner.
Go to File → Preferences → Keyboard Shortcuts (alternatively, you can press Ctrl + K + S)
In the search box, enter python.execInTerminal
Double click that result (alternatively, you can click the plus icon)
Press Ctrl + Alt + B to register this as the keybinding (alternatively, you can enter your own keybinding)
Now you can close the Keyboard Shortcuts tab
Go to the Python file you want to run and press Ctrl + Alt + B (alternatively, you can press the keybinding you set) to run it. The output will be shown in the bottom terminal tab.
Press F5 to run with Debugging
Press Ctrl+F5 to run with Debugging ignoring breakpoints.
Running the current python file as is does not have a keybinding associated by default, but you can set this with:
Ctrl+Shift+P
Type "Run Python file in Terminal"
Hover over it and click the ⚙️ icon
Double click "Keybinding"
Set your desired shortcut
I had installed Python via Anaconda.
By starting Visual Studio Code via Anaconda I was able to run Python programs.
However, I couldn't find any shortcut way (hotkey) to directly run .py files.
(Using the latest version as of Feb 21st 2019 with the Python extension which came with Visual Studio Code.
Link: Python extension for Visual Studio Code)
The following worked:
Right clicking and selecting 'Run Python File in Terminal' worked for me.
Ctrl + A then Shift + Enter (on Windows)
The below is similar to what #jdhao did.
This is what I did to get the hotkey:
Ctrl + Shift + B // Run build task
It gives an option to configure
I clicked on it to get more options. I clicked on Other config
A 'tasks.json' file opened
I made the code look like this:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "Run Python File", //this is the label I gave
"type": "shell",
"command": "python",
"args": ["${file}"]
After saving it, the file changed to this:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "Run Python File",
"type": "shell",
"command": "python",
"args": [
"${file}"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
After saving the file 'tasks.json', go to your Python code and press
Ctrl + Shift + B.
Then click on Run task → Run Python File // This is the label that
you gave.
Now every time that you press Ctrl + Shift + B, the Python file will automatically run and show you the output :)
There is an easiest way to make a shortcut for run in terminal command:
Click on the settings icon on the left bar.
Then click on Keyboard Shortcuts.
Paste python.execInTerminal in search bar on top.
Now double-click on the Keybinding column opposite the Python: Run Python File in Terminal command and set the shortcut.
I use Python 3.7 (32 bit). To run a program in Visual Studio Code, I right-click on the program and select "Run Current File in Python Interactive Window". If you do not have Jupyter, you may be asked to install it.
A simple and direct Python extension would save both time and efforts.
Linting, debugging, code completion are the available features once installation is done. After this, to run the code proper Python installation path needs to be configured in order to run the code. General settings are available in User scope and Workspace can be configured for Python language– "python.pythonPath": "c:/python27/python.exe"
With above steps at least the basic Python programs can be executed.
If you are running code and want to take input via running your program in the terminal, the best thing to do is to run it in terminal directly by just right click and choose "Run Python File in Terminal".
From Extensions, install Code Runner. After that you can use the shortcuts to run your source code in Visual Studio Code.
First: To run code:
use shortcut Ctrl + Alt + N
or press F1 and then select/type Run Code,
or right click in a text editor window and then click Run Code in the editor context menu
or click the Run Code button in editor title menu (triangle to the right)
or click Run Code in context menu of file explorer.
Second: To stop the running code:
use shortcut Ctrl + Alt + M

If you install Python language extension for VSCode, it also installs Jupyter and Pylance by default, which lets you run Python code in interactive manner.
All you have to do is use # %% before the code that you want to execute interactively.
As soon as you insert # %%, you can see that VSCode creates a new Jupyter Cell for you.
And from there you can click on the Run Cell cell menu and you can see the result.
So, all you have to do is type the following code in your VSCode,
# %%
text = 'Hello World from inline interactive Python'
print(text)
To run python3 on windows vs code:
Download the python interpreter from their official site
Install the python packages for vs code. This can be installed directly from vscode's extension manager
Verify that your python3 has been installed by running this command:
py -3 --version
Run your script with the following command from vscode's terminal:
py -3 main.py
For more information, head over here for details installation procedure.
In order to launch the current file with the respective venv, I added this to file launch.json:
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"pythonPath": "${workspaceFolder}/FOO/DIR/venv/bin/python3"
},
In the bin folder resides the source .../venv/bin/activate script which is regularly sourced when running from a regular terminal.
If you have a project consisting of multiple Python files and you want to start running/debugging with the main program independent of which file is current you create the following launch configuration (change MyMain.py to your main file).
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Main File",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}/MyMain.py",
"console": "integratedTerminal",
"cwd": "${workspaceFolder}"
}
]
}
I used my existing anaconda environment to run python. rather than using the python user appdata\local\programs\python use the anaconda install python by environment. This will give you access to all your libraries in the environment.
1. View->Command Palette->Open user settings
2. search python
a. Python: default interpreter path = c:\users\yourname\Anaconda3\python.exe
b. save the file
3. View->Command Palette->python:select interpreter
a. arrow down to your workspace name
b. select your python and environment
create a python script and run it.

I am trying out Visual Studio Code, to learn Python.
I am writing a starter piece of code to just take an input from the user, say:
S = input("What's your name? ")
When I try to run this (Mac: Cmd + Shift + B) I see the task is running with no output. I have already configured the tasks.json file for output and arguments.
print("Hello, World!")
S = input("What's your name? ")
Do I need to configure some environment variables in Visual Studio Code?
Tasks are intended for building your application. Since Python is interpreted, you don't need to use tasks.json at all to run/debug your Python code. Use the launch.json instead. I am using Don Jayamanne's Python extension for debugging and have configured the launch.json as follows:
Open the Command Palette (Ctrl + Shift + P) and write the command:
start without debugging
Then select your Environment -> Click Python. This should create a launch.json file within a .vscode directory in the current directory.
Paste the following configuration json
{
"version": "0.2.0",
"configurations": [
{
"name": "Python",
"type": "python",
"request": "launch",
"stopOnEntry": true,
"pythonPath": "${config.python.pythonPath}",
"program": "${file}",
"debugOptions": [
"WaitOnAbnormalExit",
"WaitOnNormalExit",
"RedirectOutput"
],
"console": "integratedTerminal"
}
]}
Save the file, open your python script in the editor and 'start without debugging' again. This should launch an integrated terminal where you can give input as well as see the output.
Ctrl+Shift+d, then choose integrated terminal/console.
You could install the Python extension for Visual Studio Code from the Visual Studio Code market place.
Once done, use the "Python Console" debug option to run and debug your Python code. This will launch the terminal/command window allowing you to capture input, and you wouldn't need to configure the tasks.json file for this.
Python extension: https://marketplace.visualstudio.com/items?itemName=donjayamanne.python
When you click the debug option, it takes you to the debug console instead of an actual integrated terminal. This is because the debug console only shows your code is running smoothly, but it doesn't actually allow you to add input.
I have already tried Don's suggestion and sadly it doesn't work. What you said originally by configuring the .json file was correct. With Visual Studio Code , you can only "work with" your code on a
command line. Hopefully that gets changed in the future.
In vscode Terminal tab type:
python3 file_name.py
Using Visual Studio code 1.66.0 with Pylance and launch.json config on Windows 10x64
While all my code executed in the internal debugger, the INPUT code would not. I could not use the integrated terminal for input.
I applied the configuration by Keshan Nageswaran. I did, however, have to comment out, "pythonPath":
"${config.python.pythonPath}", as VSC came back with the alert, The Python path in your debug configuration is invalid.
That being said, I am extremely grateful for the config code. I was able to respond to the input in the integrated terminal. My input was visible in the integrated terminal and reflected in the internal debugger.
type your code in Interactive window e.g.
age = input('enter a num')
print(type(age))
then execute code.
Now it is waiting to you for enter a number as age. Enter a number in empty bar and up of your vscode window that is written "enter a num" under the it, and press Enter. As a result you can see bellow aswer in interactive window:
<class 'str'>
and as follow you can see testing your code
This helped me: instead of clicking on the "Run Code" option, click on "Run Python file", in the right corner.
