builtin-import-shadowing (A004)#
Derived from the flake8-builtins linter.
This rule is unstable and in preview. The --preview flag is required for use.
What it does#
Checks for imports that use the same names as builtins.
Why is this bad?#
Reusing a builtin for the name of an import increases the difficulty of reading and maintaining the code, and can cause non-obvious errors, as readers may mistake the variable for the builtin and vice versa.
Builtins can be marked as exceptions to this rule via the
lint.flake8-builtins.builtins-ignorelist configuration option.
