Personally, I recommend you start with doctests rather than nose or unittest.
Doctests can also be run using nose, maybe that's also an idea? Nose does
doctest, unittest, and its own tests. By default, test files need to have a
prefix test_. Unless you specify this either as a

sorted returns the sorted list but you don't assign anything to it. You can
either assign it to a variable, or use the .sort method instead. Also, you
