Tips and Traps¶

Optional Pylint checkers in the extensions module

Message Control¶

1. Show ERROR messages only.

    :::bash 
    pylint -E some_script.py

2. Show ERROR and WARNING messages only.

    :::bash 
    pylint --disable=R,C some_script.py

3. Disable warning associated with a specific line.

    :::bash
    proc = sp.run(cmd, shell=True)  # pylint: disable=W1510

Configuration¶

It is suggessted that you configure pylint using pyproject.toml. Below is an example.

[tool.pylint.master]
unsafe-load-any-extension=no
extension-pkg-whitelist=numpy,cv2

[tool.pylint.typecheck]
ignored-classes=Fysom,MyClass

Similar Lines¶

Similar lines detection has a high chance of yielding false positives. It is suggested that you either set min-similarity-lines to a large value or disable check of similar lines. Please refer to the issue The duplicate-code (R0801) can’t be disabled for more discussions.

[tool.pylint.similarities]
min-similarity-lines=11
ignore-docstrings=yes
ignore-comments=yes
ignore-imports=yes

Examples¶

xinstall/data/pylint/pylintrc

.pylintrc

Please refer to settings.json for an example of pylint configuration for Visual Studio Code.
