    def pyChallenge():
      print sum(s for s in range(1000) if s % 7 != 0 and s % 5 != 0)

    pyChallenge()

Produces a TypeError, and using xrange produces a NameError (Python 3?). I have no idea what they're trying, but it doesn't work.

I assume it's Python 2 (print is a keyword, not a function).

Ah of course, a SyntaxError would take precedence over their broken builtins.
