bad-builtin / W0141#
Message emitted:
Used builtin function %s
Description:
Used when a disallowed builtin function is used (see the bad-function option). Usual disallowed functions are the ones like map, or filter , where Python offers now some cleaner alternative like list comprehension.
Correct code:
numbers = [2 * x for x in [1, 2, 3]]
print(numbers)
Problematic code:
numbers = list(map(lambda x: 2 * x, [1, 2, 3])) # [bad-builtin]
print(numbers)
