The Python standard library defines an any() function that
any()
Return True if any element of the iterable is true. If the iterable is empty, return False.
It checks only if the elements evaluate to True. What I want it to be able so specify a callback to tell if an element fits the bill like:
True
any([1, 2, 'joe'], lambda e: isinstance(e, int) and e > 0)
How about:
>>> any(isinstance(e, int) and e > 0 for e in [1,2,'joe']) True
It also works with all() of course:
all()
>>> all(isinstance(e, int) and e > 0 for e in [1,2,'joe']) False
