Pylint is a great static code analyser for Python code.
I have been using it for several years, in various projects, and it's simple to use yet very powerful.
I even contributed to Pylint by submitting a new rule a few years ago :implicit-str-concat.
For an introduction to Pylint, you can check those tutorials:
- official documentation:Tutorial &Usage
- How To Get Started With Pylint by Oliyadk @medium.com
Pylint default configuration is very reasonable, but one thing that I find missing is a simple way to switch to a "strict" mode, that would enable all optional rules. ESLint haseslint-config-strict-mode for example.
Such "strict" mode can be useful:
when bootstrapping a new project, you may want to enable all rules by default,
and progressively disable the ones you find non necessary for your projecton an existing project using Pylint, when you want to test what extra checks
can be performed by this tool, and see if it can spot bugs you missed so far
The following.pylintrc configuration file is my attempt to setup a "strict" mode:
[MESSAGESCONTROL]# Enable some checkers that are not activated by default:enable=bad-inline-option,deprecated-pragma,file-ignored,use-symbolic-message-instead,useless-suppression# Include some helpful details on errors messages for naming rules:include-naming-hint=yes[MASTER]# Informational messages ("I") should make Pylint execution fail (non-0 program return code):fail-on=I# Enable many optional extensions:load-plugins=pylint.extensions.bad_builtin,pylint.extensions.code_style,pylint.extensions.comparison_placement,pylint.extensions.consider_refactoring_into_while_condition,pylint.extensions.docparams,pylint.extensions.dunder,pylint.extensions.eq_without_hash,pylint.extensions.for_any_all,pylint.extensions.magic_value,pylint.extensions.mccabe,pylint.extensions.no_self_use,pylint.extensions.overlapping_exceptions,pylint.extensions.private_import,pylint.extensions.redefined_loop_name,pylint.extensions.redefined_variable_type,pylint.extensions.set_membership,pylint.extensions.typing,pylint.extensions.while_used,[STRING_CONSTANT]# Doc: https://pylint.pycqa.org/en/latest/user_guide/messages/warning/implicit-str-concat.htmlcheck-quote-consistency=yes[VARIABLES]allow-global-unused-variables=noI recently used this approach onfpdf2:PR #780 Hardening Pylint config

I hope this.pylintrc could be useful to others!
