Dear all, can anybody point out a situation where you really need itertools.filterfalse() ? So far, I couldn't think of a case where you couldn't replace it with a generator expression/if combination. e.g., a=filterfalse(lambda x: x%2, range(1,101)) b=(i for i in range(1,101) if not i % 2) do not return the same object type, but otherwise are achieving the same thing. What am I missing here? For sure filterfalse exists for a reason? Best, Wolfgang
