    I don't understand what they are asking for, much less come up with a solution. This question doesn't seem to focus so much on your knowledge of default arguments. Seems like there is an issue on object initialization (based on reading comments). Apparently, the goal of this question is to try to trip you up, not actually test your knowledge or teach you anything.

    in example 0, it prints "0, 2, 4" for the first even 3. but the explanation says it is going to be 2,4,6. but it says example 0 is correct. anyone else notice that inconsistency or am i missing something?

    def print_from_stream(n, stream=EvenStream()):
    stream.__init__()
    for _ in range(n):
        print(stream.get_next())
