builtin-lambda-argument-shadowing (A006)
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 lambda arguments that use the same names as Python builtins.
Why is this bad?
Reusing a builtin name for the name of a lambda argument 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.
