flake8-bugbear is a plugin for the Flake8 linter that adds checks for likely bugs and design problems in Python code. It provides opinionated warnings that don't fit in pyflakes or pycodestyle, such as bare excepts and unreliable callable checks.
Use cases
- find likely bugs in python code
- add extra lint rules to flake8
- catch bare except and other python pitfalls
- enforce code quality checks in ci
- lint python projects with opinionated rules
When to choose
- you already use flake8 and want more bug-focused checks
- you want opinionated lint rules without modifying core tools
- you need extra static analysis for python design problems
When to avoid
- you don't use flake8 as your linter
- you only want PEP 8 style checking
- you need type checking rather than linting
