That wouldn't work for set.union and set.intersection, because as
was pointed out, they're actually methods, so set.union(some_seq)
is a type error:
>>> a = {1, 2}
>>> b = {

Why do some built-in Python functions feel so differently:
For example sum(), all(), any() expect exactly one argument which is a
sequence to operate on, i.e. a list, an iterator or a generator etc.
sum([1,2,3,4])
sum(range(1, 101))
sum(2**i for i in range(10))
all([True, False])
16 matches
