zip(*matrix). It took me a while to wrap my head around this, but I think I've got it now. Thanks for the lesson.

I believe the zip(* ) is used for unzipping. <a href="https://docs.python.org/3.5/library/functions.html?highlight=zip#zip">PyDocs</a>

Nice solution; You can use a numpy function to perform exactly the same thing ;)
