I'm unable to find/execute the interactive mode in visual studio code - could you guys step-by-step me? Seems like a ridiculous question, I guess, but none of the waypoints I Googled seem to work;
"View > Other Windows > Interactive menu commands)" https://learn.microsoft.com/en-us/visualstudio/python/python-interactive-repl-in-visual-studio?view=vs-2019
I don't have "other windows"
If there's something I need to install, please let me know.
(Yes, I'm a beginner).
In VSCode, you can enter the Python interactive window in the following places:
Option 1
F1 -> Python: Create Python Interactive Window
This is the Python interactive window that comes with VSCode.
You can enter the interactive window without inputting instructions.
Please use "Ctrl+Enter" to execute the code:
Option 2
Ctrl + Shift + `
This is the cmd window that comes with the VSCode integration computer.
We need to enter the command "python" to enter the Python interactive window:
PS
For more information about using Python in Visual Studio Code, you can refer to the official VSCode documentation: Python in VSCode.
If you have the Python extension, you can use the Python Interactive feature (this is a IPython/Jupyter console, which can run parts of your code as 'cells', i.e. snippets of code executed in one go).
This article writes about the interactive window and many more possibilities of using Jupyter in VS Code: https://code.visualstudio.com/docs/python/jupyter-support-py
Best option
When editing Python code, select something and press Shift + Enter. This will open the interactive window and run your selection as a single cell.
I have personally been annoyed many times by accidentally pressing Shift + Enter instead of Enter on a line of code which (alone) would be a syntax error. Then, one day I decided to start using this feature consciously.
Terminal fallback
Press:
Ctrl+`
This opens a system shell (bash, or on Windows: Powershell or cmd).
Run python, or ipython if you have it (pip install ipython), and use the interactive window. In the terminal, you can also execute your script, by typing python myscript.py arguments.
If you type # %% in your vscode editor while editing a .py file,
then a interactive cell is created and it can be evaluated. The nice part of this is that # denotes comment in a .py file so you can save and run your code as a script

Im really quite new to coding and brand new to Python so apologies if this is a dumb question.
I'm writing basic scripts in VS Code and when I run them the result in the terminal is just..... ugly. Instead of just printing the result of my code, it prints details about my version of Windows, a little copyright notice, the full file path to my code... then eventually gets round to executing my actual code.
Is there any way for me to configure the terminal so that it just shows my code and not all the other bits? I've already seem about an extension called Code Runner, but this prints to the "Output" tab and doesn't allow any user input
If you are using PowerShell, you can add "args": ["-NoLogo"], like this to Hides the copyright banner at startup :
"terminal.integrated.defaultProfile.windows": "PowerShell",
"terminal.integrated.profiles.windows": {
"PowerShell": {
"source": "PowerShell",
"icon": "terminal-powershell",
"path": ["C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe"],
"args": ["-NoLogo"],
}
},
And you also can change the value of console in the launch.json file. But internalConsole does not accept the user input. And externalTerminal will prompt a cmd window out of the VSCode.
Maybe you can try Jupyter code cells:
https://code.visualstudio.com/docs/python/jupyter-support-py
Try jupyter on visual studio code interface
https://code.visualstudio.com/docs/datascience/jupyter-notebooks
You have to follow these steps:
install python extension for vs code.
python extension
2.After installing reopen vs code and you will see a play button at right-top corner.
play button
3.Click that button and run your code!
go to settings
search for terminal
find Code-runner : Run in Terminal and turn that off.
I'm using Visual Studio Code, and I'd like to have a REPL that I can run single Python instructions in. I've found some year-old Microsoft documentation on this that says select the View > Other Windows > Interactive menu item, but there is no Other Windows item in my version of VS Code (1.44.2).
Does VS Code have a REPL feature, or do I have to run python.exe directly from the Terminal pane?
You are looking at the wrong documentation. That's for Visual Studio, not Visual Studio Code. They are annoyingly similarly named, which can be confusing, but they are two completely different IDEs.
The correct docs for VS Code is here:
https://code.visualstudio.com/docs/languages/python
There is a section for running Python codes on the Terminal:
https://code.visualstudio.com/docs/languages/python#_run-python-code
You can use the standard Python console.
Install the Python extension for VS Code
Setup and select the correct Python environment
Open the Command Palette then "Python: Select Interpreter"
Next, highlight the line you want to run, then right-click
Select the Run Selection/Line in Python Terminal
It should open up a Terminal panel and run your code in Python console
You can then keep right-clicking > Run and it will execute on the same session
There's also an option to run the entire file.
See the Run Python Code section of the docs for more info.
You can open the command palette and enter python: Start REPL
This will open the REPL.
In R Studio, Matlab, and in some Python IDEs (like Thonny) you can see a list of the variables in your environment, together with some summary information like values, type etc.
Is there a way to do this in VSCode without going into debugging mode?
Seems like the closest as it gets to the RStudio Environment window is by installing Jupyter. Then you can type #%% in your .py file and a small "Run Cell" button will appear. Running the cell will open the "Python Interactive Window". There you can click the "See Variables Active" button to open up the Variable Window and see your variables... still a bit painful in comparison with RStudio, this should be integrated in VScode's IDE.
See steps here:
https://code.visualstudio.com/docs/python/jupyter-support-py#_variable-explorer-and-data-viewer
VS Code has an IPython mode with a dropdown box called Variables that basically does exactly this.
To enter IPython mode all you need to do is highlight a piece of code and hit Shift+Enter
The first time you do it there might be a bit of setting up to do but it was pretty easy to get it working on my Mac. Not sure what it's like on Windows/Linux though
Note: When I use VS Code I open it from the terminal (simply enter the command 'code') after I've activated my conda environment. That way the IPython interpreter uses my preferred conda environment when it launches.
I downloaded and installed Visual Studio along with Anaconda to get access to all of the packages that come pre installed with Anaconda. I am trying to figure out how to run code such that it runs in the interactive shell. Right now when I hit F5 an Anaconda 3 cmd line window comes up with the prompt "Press any key to continue..." comes up. My question is: how can I make it so that when I hit F5 my code is executed in the interactive Python shell much like it does on the basic IDLE that comes with Python.
This seems like a question that a simple Google Search could fix, but for some reason I cannot find the answer. I've done some google searching, and I watched the Visual Studio python official Microsoft series about it. One of the videos touched on using the interactive shell, but even in the video, when he clicked the Start (Run) button, the code ran in what looked like the command line.
I have used IDLE in the past, and now I think it is time to make the change to a bigger IDE. I love the code completion and templates of visual studio, and I can't wait to solve this (noob) question.
Thanks
I am struggling with this as well. There is a Visual Studio Shell command execute file in Python interactive which is bound to Shift+Alt+F5 by default.
This works: if the focus is in a code window then the current file is executed. If the focus is in the Solution Explorer window, the file selected as "Startup item" is executed. There seems to be a glitch however: Some import statements from the specific file which work fine on the standard Ctrl+F5 will fail on Shift+Alt+F5. I need to figure out why this is the case and will report here.
EDIT: Once in the interactive windows, change the working directory to the folder containing the project: os.chdir etc. Then import your-filename works flawlessly. So I assume that there is some problem with selecting the working directory while executing Shift+Alt+F5.
Add
import os
os.chdir(r"C:\My\script\\path\")
to the top of your script.
Then Shift+Alt+F5 works as expected.
I'm not sure if it's the best way to do that, but here is what I do to quickly run Python script in Interactive Shell in Visual Studio 2017:
Add #%% sequence at the beginning of *.py file
Press Ctrl+Enter having cursor active in text editor
Code from #%% to end of file (or another #%%) will appear on Interactive Window
#%% is basically beginning of the cell. Cell is a part of code you would want to run at once in Interactive Shell. Cell begins with #%% and ends with another #%% which initializes another cell.
For example: you have following code in Visual Studio:
#%% Cell 1
print("Hello world1")
print("Hello world2")
#%% Cell 2
print("Hello world3")
When you click/focus on third line and press Ctrl+Enter you will run second and third line in Interactive Window.
To make a same experience like in c# where you can use F5 to start debugging python in Visual studio 2017 , you need to
1) create a new visual studio project ( ctrl + shift + N)
2) Select python as project type
3) Now you can create new python file ( *.py) and start code python ( ctrl + N)
4) Now you can right click the py file that you just created and use "set as startup file" command
5) Hit F5 to start python IDE debug experience ( breakpoint , inspect value , data type etc) , see below screen shoot
Is there a interface in Pycharm where we can simply type in some commands and run it ?
Something like in Matlab, we can type in "a = 1; b = 2; c = a+b" then we get ans=3.
Thanks
PS: we know we can create a python file in Pycharm and run it, e.g., "a = 1; b = 2; c = a+b; print(c)" but it is not as convenient as a command window.
Short answer from the docs:
To launch an interactive console
On the main menu, choose Tools | Run Python console.
Description:
REPL console
PyCharm also helps those who love the full control of an
interactive console: on the Tools menu, you can find commands that
launch the interactive Python or Django consoles. Here you can type
commands and execute them immediately. Moreover, PyCharm's interactive
consoles feature syntax highlighting, code completion, and allow
viewing the history of commands (Ctrl+Alt+E or Up/Down arrows while in
the editor).
PyCharm also makes it possible to run in console source code from the
editor — just make your selection, and then press Shift+Alt+E (Execute
selection in console on the context menu of the selection).
Independent of Pycharm, you can also access the REPL in the terminal (or cmd shell on Windows) by typing
python
at the prompt.
In PyCharm, you navigate to the View -> Tool Windows menu and toggle the Terminal window See image here. It will likely show up at the bottom of your IDE window.
Another very good (and more general option) is to use IDLE. From its Wikipedia entry...
IDLE is intended to be a simple IDE and suitable for beginners, especially in an educational environment. To that end, it is cross-platform, and avoids feature clutter.
It ships with basically every standard version of Python since 1.5.2 so I'm pretty sure you have it available on your system (I've checked with Linux and Mac OS X).
To fire up IDLE in Python2, enter: /path/to/python/bin/idle where /path/to/python/bin is where you find the Python executable.
For Python3, use idle3 instead.
You should see a new separate terminal window open up (with syntax highlighting and all!)See image here.
Find the attached screenshot..
You can observe the o/p of the editor in Run window.
You can also find Python Console and Command Terminal at the bottom of the Pycharm.
