loop-variable-overrides-iterator (B020)

Derived from the flake8-bugbear linter.

What it does

Checks for loop control variables that override the loop iterable.

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.

items = [1, 2, 3]

for items in items:
    print(items)

Use instead:

items = [1, 2, 3]

for item in items:
    print(item)
