The Python built-in function any(iterable)
can help to quickly check if any bool(element)
is True
in a iterable type.
>>> l = [None, False, 0]
>>> any(l)
False
>>> l = [None, 1, 0]
>>> any(l)
True
But is there an elegant way or function in Python that could achieve the opposite effect of any(iterable)
? That is, if any bool(element) is False
then return True
, like the following example:
>>> l = [True, False, True]
>>> any_false(l)
>>> True
There is also the all
function which does the opposite of what you want, it returns True
if all are True
and False
if any are False
. Therefore you can just do:
not all(l)
