loop-variable-overrides-iterator (B020)#

Derived from the flake8-bugbear linter.

What it does#

Checks for loop control variables that override the loop iterable.

Why is this bad?#

Loop control variables should not override the loop iterable, as this can lead to confusing behavior.

Instead, use a distinct variable name for any loop control variables.

Example#

items = [1, 2, 3]

for items in items:
    print(items)

Use instead:

items = [1, 2, 3]

for item in items:
    print(item)
