Real-time linting of Python with VSCode

Question

Recently I'm using VSCode as my Python IDE, and I install DonJayamanne/pythonVSCode, which supports linting. However, the linter only works when saving, but what I want is real-time linting. The workaround suggested by the author is to set files.autoSave to on, so that the linter will work whenever the file is automatically saved. There's a relevant discussion on Github, for your reference.

Since I don't want to turn on auto-save function, is there any way to do real-time linting of Python with VSCode? Or is there any suggested extension?

Enable format on save option in UI setting globally.

EDIT3, 13 Apr 2024 Its just enough for 1.88.1 version

{
    "editor.formatOnSave": true
}

Just only use this config to real time linting.

{
    "python.defaultInterpreterPath": "/usr/bin/python3",
    "editor.formatOnSave": true
}

Installed extensions are

• python
• pylint
• pylance
• python debugger
• autopep8

EDIT1 Update 4 Jul 2022 New version of python extension deprecates "python.pythonPath" and suggest to use this instead.

"python.defaultInterpreterPath": "/usr/bin/python3",

Put these lines in .vscode/settings.json

{
    "python.linting.pylintEnabled": true,
    "python.linting.enabled": true,
    "python.pythonPath": "/usr/bin/python3",
    "editor.formatOnSave": true
}

And install autopep8 package.

Use pip to install it

python3 -m pip install autopep8

Or in Debian based as python3-autopep8 exists in repo you can run

sudo apt install python3-autopep8

And then python linting on vscode will work.

Also, the Warning menu will activate.

Hint that I set run linter onsave.
