i have a python file with the following content saved on my machine:
types_of_people = 10
x = f"There are {types_of_people} types of people"
binary = "binary"
do_not = "don't"
y = f"Those who know {binary} and those who {do_not}."
print(x)
print(y)
print(f"i said: {x}")
print(f"I also said: '{y}'")
hilarious = False
joke_evaluation = "Isn't that joke so funny?! {}"
print(joke_evaluation.format(hilarious))
w = "This is the left side of ..."
e = "a string with a right side."
print(w + e)
When i open this file with Python 3.7 from within Visual Studio Code i get the following error:
/usr/local/opt/python/bin/python3.7 /Users/andree/Desktop/test.py
File "<stdin>", line 1
/usr/local/opt/python/bin/python3.7 /Users/andree/Desktop/test.py
^
SyntaxError: invalid syntax
In the following screenshot you can see the command i use to run the file and also which python extension i use.
But running the file from within my terminal with python3 test.py works just fine.
Does anyone know what the problem is when running it from within VS Code?
Think this is a bug of VS Code.
When you use "run selection/line in python terminal" command, VS Code starts python interpreter and doesn`t quit it after completion.
You should use exit() command in python interpreter window to end python session.
After that "run python file in terminal" will work fine.
Looks like this is a bug in VS Code.
When i create a new file, assign python language to it and then save it then it works when i run the python file from within the editor.
But when i create a new file, assign python langauge but dont save it, execute "Run Selection/Line in Python Terminal" afterwards save it and then run "Run Python file in Terminal" it doen't work. So this seems to be an VS Code related issue.
The problem for me was that I accidentally used
Shift
+
Return
which executed the python program, when in fact I meant to hit
CTRL
+
Return
to move to the next line without touching the mouse.
Using exit() command in the console worked.
It's a probable bug in VS code. I don't know why there hasn't been a patch for this.
After typing exit() in the terminal, the rerun should work fine. You could also try Ctrl+F5 to run in a debug mode.
Disable terminal.integrated.inheritEnv in settings. This was suggested by VSCode for me and it worked.
I got the same issue, simply restart the Vs-Code it works for me !!
I experienced this issue when attempting to change my default terminal settings. I continually ran into a situation where the "Run Python File in Terminal" command would result in syntax errors while the "Run Selection/Line in Python Terminal" command would error but still display the results. Irritating to say the least.
Here's the settings I utilized to resolve the syntax errors issue.
Note: Enabling Pylint did not resolve my issue, in fact it continued to pop-up even after selecting to enable it. These specific user/workspace/folder settings resolved that issue for me too.
Note: Since the terminal defaults to Powershell, you have to type Python to enter manual commands directly into the python terminal and exit() to close it to allow the python file to run properly again.
USER SETTINGS
{
"terminal.integrated.shell.windows": "C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe"
}
WORKSPACE SETTINGS
"settings": {
"terminal.integrated.shell.windows": "C:\\Python3.7.2\\python.exe",
}
FOLDER SETTINGS
"python.linting.pylintEnabled": true,
"python.pythonPath": "C:\\Python3.7.2\\python.exe",
I found a fix for this, install "pylint". I had a pop-up message in Visual Studio that asked me to download this extension. I did and after that I was able to run my code!
I got the same issue, but the code ran for me when I ran it using 'Start without debugging'. This can also be done with the shortcut CTRL + F5.
I found the issue is generated by trailing spaces after the loop functions.
So what I do to alleviate it is add an empty
print ()
statement at the very end of the script

I tried to run a python program in VS Code. But my program didn't run. The terminal opened and a weird arrow was there in the terminal. This is the screenshot of that.
This is the weird arrow and the program is not running. Any ideas why this is happening and how to fix it?
Thanks in advance.
Firstly, the arrows are included in the default python IDE means that VScode ran the command to execute your code. Give your pc a restart. Now, let us check if python is working or not or VS code is having some trouble. Type the following command in cmd to execute the code-
python "$PATH"
Rember to replace $PATH to the path of the file i.e where your file is stored. For eg. I've my python files stored in D drive in a python folder, so I'll use-
python "D:\Python\Hello.py"
If this works, python is working fine and if not, try reinstalling python and check the box which says Add python to Path or Environment variables. Then open VS code try to run the program again. But click the button only once and be patient because clicking it multiple times causes execute the same command again and cause a problem. It's my personal experience. Wait 5 minutes. Not works. Don't worry, there's a problem with the run extension you are using. I'll recommend the Code runner by Jun han. I personally use it. Type this in the extension search box-
formulahendry.code-runner
Install it and then try again.
Kill the terminal, and retry. If not work, restart the VSCode.
However simple my python script is, I cannot get it running inside VSCODE Terminal by clicking on the "RUN" icon at the top right, whereas it runs fine when called from a CMD window
I had the same problem, this thread helped me I get a syntax error about File "<stdin>", line 1
You are now working inside your Python shell (>>>) while the code you are running (& python "FILENAME.py") is no Python, therefore syntax error.
exit()
to exit the python shell and return to the PowerShell environment.
Simply
python
to enter again, to run python code directly
It seems python is not recognized in your PATH variable. I think the 2 ways to fix are to find your python filepath and adding it your User Variables:
Control panel > System > advanced settings > Advanced tab > Environment Variables
select PATH and then click edit..
in a new line add the path to your python installation (ie C:\Users\YOURUSERNAME\AppData\Local\Programs\Python\Python38-32)
OR, not sure this works out of the box but you could:
install Python module from within VS Code, published by Microsoft
After editing the PATH as suggested by #mah111, I needed to restart VSCODE application
When using VSCode with the Python plugin I'm experiencing a very annoying bug, which is known in the community but was hoping to find a workaround.
Basically, when I run a single line execution with VSCode, the terminal enters into python interpreter and executes the line. After this I'm unable to execute the file in the terminal as VSCode doesn't automatically exit the python interpreter but I have to do so manually with quit() or CTRL+D. This can be quite annoying.
>>> /usr/bin/python3 /home/debian/Documents/Tutorial/tutorial.py
File "<stdin>", line 1
/usr/bin/python3 /home/debian/Documents/Tutorial/tutorial.py

SyntaxError: invalid syntax
In order to replicate the issue use VSCode in a linux environment and execute a single line of code by pressing Shift+Enter and then try to run the file by pressing the rune file button on the top right.
A fix would be that VSCode would run the single line executions in a seperate terminal, as with PyCharm or have it exit the interpreter prior to executing the file.
So I found two workarounds.
The first one is to run the file without debugging by using CTRL+D
which can still be annoying as it takes a bit longer to load.
The second one is to install the extensions "Code Runner" Code runner lets you run the file in a seperate terminal. And add the following to your settings file to have it working just like PyCharm.
"code-runner.runInTerminal": true,
"code-runner.executorMap": {
"python": "python3"
},
"code-runner.saveFileBeforeRun": true
The question is open for more answers if anyone find a way to get this working by edditing some settings without the use of extensions.
I am well aware of the thread How to execute Python code from within Visual Studio Code
But none of them shows how to get the >>> python shell running with the file imported. Cuz I would like to call functions separately.
I understand that I can get the python shell going by simply typling python in the terminal but the functions in the python file have to manually imported everytime.
Is there a way to run files in VSCode like in IDLE?
you can run the file in an interactive mode in VSC code terminal by using the parameter -i :
python -i py_file.py
Install the Python Extension, then press Ctrl+Shift+P (Command+Shift+P) and type Python: Start REPL. Click the command, and you'll get an interactive Python console.
Assuming you have the official Python extension installed, you can search the command list (Ctrl+Shift+P) for "Python interactive" and you'll see several options that allow to do different variations of this:
Not sure if this was figured out or not, but I was having a similar question. How to simply use something like IDLE (the known '>>>' shell prompt) inside VSCodesee w/o chasing down plugins and their settings? I noticed that no answer was marked confirmed and although insightful, not what I was looking for.
I use Mac and while trying different things to address this, I found that by using/copying the path in the Python Launcher settings I got what I was looking for. Then, I validated the equivalent for Windows. Please see below.
Windows:
If you are using Windows, from your Terminal pane/window in VSCode, enter the path to your python.exe, including the executable name. It is located within the "User > AppData" directory.
For example: C:\Users\YOUR_USER_ID\AppData\Local\Programs\Python\Python310\python.exe
Note that AppData is a hidden folder, so may have to change your view settings in Explorer to show Hidden Items.
MAC:
If you are using MAC, from your Terminal pane/window in VSCode, enter the path to your interpreter
For example: /usr/local/bin/python3
Note: You can also do this directly from a CMD, PowerShell or a Terminal(Mac) window without having to launch IDLE, VSCode or any other coding/scripting app.
To build on the answer already provided, you can automatically run in interactive mode by changing your settings:
Go under File>Preferences>Settings. Search for "arguments" in the search bar. Then under "Python › Terminal: Launch Args", click on the link "Edit in settings.json".
Once settings.json is open, add "-i" with the quotation marks. It should look something like that:
{
"workbench.colorTheme": "Default High Contrast",
"terminal.integrated.localEchoEnabled": "off",
"terminal.integrated.shellIntegration.enabled": false,
"python.terminal.launchArgs": [
"-i"
]
}
Now, it will pass the argument -i every time you run.
I have downloaded Atom.io for window and done setup successfully, then I download the package for running codes. but the Python result always come with an error like the picture.
Can you help me on this issue? Thank you
Try typing in:
python myprogram.py
However, you will still receive an invalid syntax error because:
print(*hi*)
should be:
print('hi')
Also, if you want to enter the python terminal, type:
python
Then you can type these commands (i.e. print("hi")) directly into the terminal instead of creating a .py file and running it.
One final point, I use the following instructions to add the python to PATH: how to add python to path in windows.
You can check this Stack Overflow thread for more details.
However, if you just want to play around with Python in Windows:
Download Python and install it.
Go to Start > type "IDLE" and click "IDLE (Python)".
Start coding! For example, type print("Hello, world!") and press the Enter key.
My first contact with Python was IDLE and I liked it a lot. Have fun!
It looks like you're running this from powershell. You can tell it's powershell because it says "Windows Powershell" on the first line of the output. Here's what I would do if I were you:
To start the python shell type python and press enter.
1a. Enter what you want to run in python, print('test') for example
If you want to get out of the python shell, enter ctrl-z and press enter to return to powershell.
To run python scripts use the command python {script}.py
Installing python on path
If you tried the above steps and got an error to the effect of "I don't recognize python" you should ensure that python is correctly installed in your PATH.
You can follow these instructions to install python correctly.
