no-redundant-list-comprehension¶

Collection: fixit-extra Autofix: No Python: Any

Prefer generator expressions inside any() and all(). Replacing a list comprehension changes eager evaluation into lazy short-circuiting, so side effects in later iterations may no longer run.

Message¶

Unnecessary list comprehension inside {func}(). Use a generator expression instead.

Valid examples¶

any(val for val in iterable)

all(val for val in iterable)

frozenset([val for val in iterable])

max([val for val in iterable])

min([val for val in iterable])

sorted([val for val in iterable])

sum([val for val in iterable])

tuple([val for val in iterable])

def any(value):
    return value

any([val for val in iterable])

Invalid examples¶

any([val for val in iterable])

all([val for val in iterable])
