Sure, but there are different levels of cheating. Using a
general-purpose programming language and its standard library isn't
usually considered cheating, but using a language or library that's
specifically designed for this purpose is less about "hey look how
simple this is" and more about "hey look how awesome this lang/lib
is". Which is a perfectly reasonable thing to brag; Python is
beautifully expressive in the general case, but there are some amazing
tools for special purposes.

So I wouldn't call it cheating; it's a demonstration of the
expressiveness of numpy.
