How can I change the Python version in Visual Studio Code?

Python Problem Overview

These are my settings:

User Settings

{
    "atomKeymap.promptV3Features": true,
    "editor.multiCursorModifier": "ctrlCmd",
    "editor.formatOnPaste": true,
    "python.pythonPath": "python3",
    "command": "python3",
}

Workspace Settings

{
    "python.pythonPath": "${workspaceFolder}/env/bin/python3.6",
    "git.ignoreLimitWarning": true
}

tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "0.1.0",
    "command": "python3",
    "isShellCommand": true,
    "args": ["${file}"],
    "showOutput": "always"
}

If I use the debug console, the version and path is right:

But the output always defaults to "python2.7", no matter what I do.

How can I fix this?

Python Solutions

Solution 1 - Python

Under the view menu select 'show command pallet'. One of the commands you can then select from the command palette is 'Python: Select Interpreter'. Selecting this option will allow you to choose which version of python to use.

Solution 2 - Python

UPD. First, read the update #1 part in the bottom

(Try update#1 first) Looking at your screenshots I see you are using Code Runner extension. And I guess that is the way you are launching your programs. I don't know how it works internally, but adding this line into Code-Runner extension setting.json file fixed it:

"code-runner.executorMap.python": {...
"python": "python3 -u",
...}

Found it in Code-Runner GitHub repository: https://github.com/formulahendry/vscode-code-runner/issues/366

If you type "python --help", you'll see "-u" flag stands for "unbuffered binary stdout and stderr..." - don't know why it matters here.

Update #1. This became not so convenient further - I started using python's virual environments and the solution above couldn't launch these environments, cause python3 (symlink) is always linking to the same python environment.

The solution here is to use Code-Runner's supported customized parameters, so you should change "python" line in it's settings.json to:

...
"python": "$pythonPath $fullFileName",
...

Solution 3 - Python

Tot's answer is what worked for me on windows 10, with a few modifications.

File -> Preferences -> Settings
Type in "python.pythonPath" in the search bar.
Change it to what you normally run python with from the command line. If you have your Path environment variable set, that's just python. If not, it's likely the full path to the executable.

Solution 4 - Python

This solution is for Mac and Linux:

To change your Python version from 2.7 to 3 do this:

In Vscode click on file > preferences > settings.
On the right side click on the ... (the three dots) and select (open settings.json)
In the search bar type code-runner.executorMap.
You can only change the settings on the right side.
After the last setting type a comma then "code-runner.executorMap" and hit enter, this will copy all the settings from the default file.
Look for "python" and change the command next to it to "python3".
Save the changes and you should be good to go.

Solution 5 - Python

VS Code's terminal using a different python interpreter than the one you've selected

~~By default, it doesn't know about your interpreter, and will initialize using the default .bashrc or equivalent in the OS.~~

I found two relevant settings from an issue in Feb 2021. Checking the second option Python > Terminal: Activate Environment enables automatic activation of virtual environment:

In settings.json it is called "python.terminal.activateEnvironment": true.

Update (8 Aug 2021): Today when I opened the terminal from VS Code on Windows, it automatically inserted a line of code & C:/Users/[UserName]/[venv]/Scripts/Activate.ps1 to activate the appropriate environment associated with the selected python interpreter! It appears the aforementioned settings is now the default behavior. While there are changes to Terminal behavior in the release notes of July 2021 (version 1.59), I don't see virtual environment activation being explicitly mentioned.

The new behavior is documented here, in "Environments and Terminal windows".

`"python.pythonPath"` has been deprecated

Therefore most previous answers are outdated. Use "python.defaultInterpreterPath" instead:

> 5. Added python.defaultInterpreterPath setting at workspace level when in pythonDeprecatePythonPath experiment. (#16485)
> 8. Show python.pythonPath deprecation prompt when in pythonDeprecatePythonPath experiment. (#16485)

> 2020.7.0 (16 July 2020)
> 9. Prompt users that we have deleted pythonPath from their workspace settings when in Deprecate PythonPath experiment. (#12533)

> 2020.5.0 (12 May 2020)
> 6. Do a one-off transfer of existing values for python.pythonPath setting to new Interpreter storage if in DeprecatePythonPath experiment. (#11052)
> 8. Added prompt asking users to delete python.pythonPath key from their workspace settings when in Deprecate PythonPath experiment. (#11108)
> 12. Rename string ${config:python.pythonPath} which is used in launch.json to refer to interpreter path set in settings, to ${config:python.interpreterPath}. (#11446)

> 2020.4.0 (20 April 2020)
> 13. Added a user setting python.defaultInterpreterPath to set up the default interpreter path when in Deprecate PythonPath experiment. (#11021)

If you wish to set a default python interpreter for all workspaces, open settings with Ctrl+Shift+P, Preferences: Open User Settings and search for Python: Default Interpreter Path. Otherwise, if you want to set it for only the current workspace, use Preferences: Open Workspace Settings instead.

In your case, you wish to set it to ${workspaceFolder}/env/bin/python3.6. If you edit settings.json directly instead of using the GUI:

{  
  "python.defaultInterpreterPath": "${workspaceFolder}/env/bin/python3.6"
}

Detailed instructions can be found in the documentation "Manually specify an interpreter", including using environment variables as the interpreter's path.

Solution 6 - Python

In VSCode there are two paths of python:

Path that is used when you the python code using green play button up in the top right corner. This path can be set under CTRL+SHIFT+P Python: Select Interpreter.

Path that is used when you type "python" in the terminal, and this is in "Environment Variables" in Windows 10 (Similar locations under Linux and Mac). In Windows 10 you can choose to have several Python versions, usually under C:\Users\YourName\AppData\Local\Programs\Python\Python##. Just make sure you change Environment variables C:\Users\YourName\AppData\Local\Programs\Python\Python## and C:\Users\YourName\AppData\Local\Programs\Python\Python##\Scripts accordingly. This will also affect which pip you use, i.e. a pip that belongs to Python 3.8, or a pip that belongs to Python 3.9. Terminal in VSCode in general pertains to your default terminal I think. So in Windows 10 when you type "python" in CMD Line, it should be the same version as VSCode terminal.

For sanity purposes you should make sure that both "Python: Select Interpreter" and the system environment variables point to the same version of Python.

Bonus goodie in Windows 10. If you don't have environment variable setup, and you type 'python' in VSCode terminal, it'll point to C:\Users\YourName\AppData\Local\Microsoft\WindowsApps\python.exe, which just opens up python link in Windows AppStore .

Solution 7 - Python

Late answer really, if you find difficult to set the python version in VsCode,

If the interpreter didn't show the envname/bin/python or any desired path you want, then go to

VSCODE main page -->file-->preference-->settings
select the ... on the right corner side. You'll see USER SETTINGS, WORKSPACE SETTINGS, YOURAPP_NAME_SETTINGS. click on the your_app_name.

> "python.pythonPath": > "/home/Jhon/AllWorksUbuntu/Projects/VX-350/envname/bin/python"

Play on the above to set the correct path. You're good to go!!!

Solution 8 - Python

Several of the answers here explain some good options but below are my top 2 recommendations.

Bottom Screen Navigation (ease of access)

This is my quickest approach, however, it isn't always available for first-time users. If you're already using Python in VS Code, this is usually the simplest way to reach the Python: Select Interpreter menu. On the bottom left of your screen, look for "Python X.X.X". This is the currently detected/configured version of Python in your project, and clicking it brings you to the interpreter menu to change the Python version you're using. At the time of writing, I was using Python 3.9.1 in the snippet below:

Command Palette

As @jmh denoted in his answer, you can also use the 'View' tab to navigate to the Command Palette. In the Command Palette, search for Python: Select Interpreter to then bring about the same menu denoted above.

Happy coding!

Solution 9 - Python

Worked for me (linux user);

Assuming that you have other python versions installed in your system:

Kill the old terminal
Open a new terminal
In the new terminal instead of write "python" to select the interpreter write "python3" or "python3.8"

Looks like put only 'python' will always bring python 2.

Solution 10 - Python

Just a preface: VS code was working fine (Using Python 3.x) and seemingly out of the blue it started using Python 2.7. The input() function would not convert the input to a string and that's when I realized what was happening. Typing Python in the terminal window showed 2.7 was running.

For me....

Even though "python.pythonPath" was pointing to a seemingly correct location (C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64), one of my environment variables was pointing to C:\Users\Mike.windows-build-tools\python27.

I deleted the environment variable and reinstalled Python 3.8 from the Microsoft Store and it immediately installed. I got a message from VS Code (it was running) that 3.8 got installed. I clicked Terminal/New Terminal, typed Python and it showed version 3.8. Typed 'Python xxx.py' and the code started working as it had been.

Solution 11 - Python

In my case, I checked the python version using

python --version

It showed python 2.x even though my interpreter path was 3.x. So uninstalled python 2.x from my computer through control panel. Then it worked fine for me.

Solution 12 - Python

One thing that can also be missed is the shell profile you are using in your terminal where you see the wanted python version vs the profile in your VS Code.

Hold cmd + p and write >Terminal: Select default profile
Select bash or whatever you used to install the python3 version in the terminal at the global level.
Closs the terminal and VS Code and then open it again, this time VS Code will pick the correct version

Solution 13 - Python

In Vscode you can go to preferences > settings, then on the right menu click on the first icon which is JSON. Look for "python.pythonPath" and "python.defaultInterpreterPath" and change the path. To find python3 path, open terminal and execute python3 dummyname. Actually you'll face an error but the point is it will show you the path!

Solution 14 - Python

from the Lower left corner, click on the python, then vscode will navigate you to all python version that installed in your system, and select the right one for you.

Solution 15 - Python

Windows: Use py -3.6 --version or to create virtual environment py -3.6 -m venv venv36

Solution 16 - Python

Updating @Isabella answer, using current VSCode 1.65.1 and current python launcher, you can use py -version, for example py -3.8.

Thus, you can make a folder .vscode containing a single file name called settings.json containing

{
  "python.defaultInterpreterPath": "py -3.8",
}
