  4. Python Linting

Linting within the extension is supported on the following:

Pylance isn't in control of these linters, the Python extension is, and if these settings I'm suggesting aren't working, then that's probably an issue with it. Pylance itself has configuration, and a project-level config via pyrightconfig.json (and pyright is what you'd actually want to use in CI, as it is a CLI tool).

  • Pylint (this is the default linter used)

Set PyLint command-line options PyLint, a widely used tool that checks for errors in Python code and encourages good Python coding patterns, is integrated into Visual Studio for Python projects. Fully customizable Modify your pylintrc to customize which errors or conventions are important to you. The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature. More about message control (FAQ).

Paths

Linter

All samples provided here are for windows.
However Mac/Linux paths are also supported.

Note: You could enable all of the above linters if necessary. Or just one or two of them.
This can be achieved by enabling/disabling individual linters.

Lint as you type

Linting as you type can be enabled by turning on the ‘auto save’ feature in Visual Studio Code…
Follow the instructions here to turn on auto save.

Enable/Disable Linting

By default linting is enabled and uses pylint.
If you wish to turn this off, you could do so either in the User Settings or the Workspace Settings file.
Enabling/disabling could be done by configuring the following property in either one of (User or Workspace settings file) as follows:

The extension will run the linter when ever a file is saved.
This can easily be turned off, once again either within the User or Workspace Settings files with the following configuration change:

Maximum number of messages

The default maximum number of messages displayed in Visual Studio Code is limited to 100.
If this is to be altered, then change the following configuration settings either in the User or Workspace settings file:

Pylint

As mentioned previously, this is the default linter used by the extension.

Installing PylintFor this to work properly ensure pylint is installed locally.
You can easily install pylint as follows:
pip install pylint

Install

Enabling/Disabling pylintIf the pylint linter is not to be used by the extension, then disable it as follows either in the User or Workspace settings file:

Custom PathThis is generally unnecessary. As the Extension will resolve the path to the formatter based on Python executable being used or configured in python.pythonPath of settings.json. If this cannot be found, then the formatter will be resolved based on the current environment Path settings.

If this is not the case or you wish to use another version of pylint, all you need to do is configure the path as follows either in the User or Workspace settings file:

Pylint Category MappingMessages generated by pylint fall into the following categories:

  • convention, refactor, warning, error, fatal
    Visual Studio Code supports the following categories in linting:
  • Hint, Error, Information, WarningBy default the extension maps pylint “convention” to “Hint”, and so on.
    These mappings can be altered either in the User or Workspace settings files as follows:

Custom ConfigurationYou can customize the linter by providing a configuration file for pylint and placing it in the necessary location.
For instance you could place a pylintrc or .pylintrc file in the workspace folder.For further details please refer Pylint Command Line Options

Pylint Plugins or custom arguments to PyLintCustom plugins such as pylint plugin for Django can be easily used by modifying the User or Workspace settings as follows:

Pep8

As mentioned previously, usage of this linter is turned off by the extension.

Installing Pep8For this to work properly ensure Pep8 is installed locally.
You can easily install pep8 as follows:
pip install pep8

Enabling/Disabling pep8If the pep8 linter is to be used by the extension, then enable it as follows either in the User or Workspace settings file:

Custom PathThis is generally unnecessary. As the Extension will resolve the path to the formatter based on Python executable being used or configured in python.pythonPath of settings.json. If this cannot be found, then the formatter will be resolved based on the current environment Path settings.

If this is not the case or you wish to use another version of pep8, all you need to do is configure the path as follows either in the User or Workspace settings file:

Custom ConfigurationThe options are read from the [pep8] section of the tox.ini file or the setup.cfg file located in any parent folder of the path(s) being processed.
For further details refer the following Options.

Flake8

As mentioned previously, usage of this linter is turned off by the extension.

Installing Flake8For this to work properly ensure Flake8 is installed locally.
You can easily install flake8 as follows:
pip install flake8

Enabling/Disabling flake8If the flake8 linter is to be used by the extension, then enable it as follows either in the User or Workspace settings file:

Custom PathThis is generally unnecessary. As the Extension will resolve the path to the formatter based on Python executable being used or configured in python.pythonPath of settings.json. If this cannot be found, then the formatter will be resolved based on the current environment Path settings.

If this is not the case or you wish to use another version of pep8, all you need to do is configure the path as follows either in the User or Workspace settings file:

Custom ConfigurationThe user settings are read from the ~/.config/flake8 file (or the ~/.flake8 file on Windows).
At the project level, a tox.ini file or a setup.cfg file is read if present. Only the first file is considered. If this file does not have a [flake8] section, no project specific configuration is loaded.
For further details refer Configuration.

mypy

As mentioned previously, usage of this linter is turned off by the extension.

Installing mypyFor this to work properly ensure mypy is installed locally.
You can easily install mypy as follows:
pip3 install mypy-lang

Enabling/Disabling mypyIf the mypy linter is to be used by the extension, then enable it as follows either in the User or Workspace settings file:

Custom PathThis is generally unnecessary. As the Extension will resolve the path to the formatter based on Python executable being used or configured in python.pythonPath of settings.json. If this cannot be found, then the formatter will be resolved based on the current environment Path settings.

Linter Pylint

If this is not the case or you wish to use another version of mypy, all you need to do is configure the path as follows either in the User or Workspace settings file:

Custom ConfigurationCustom command line arguments can be passed into mypy just as with the other linters using the setting:

pylama

As mentioned previously, usage of this linter is turned off by the extension.
