In the most naive uses, map appears to have no advantage over list
comprehension; but one thing that map can do that list comprehension
still can't do without a walk around the park:
def foo(func, args):
g = lambda x: x+1
return [func(g, x) for x in args]
foo(map, [[4, 6, 3], [6, 3, 2], [1, 3, 5]])
I'm not going to argue how often that would be useful though.
