Unit test for problem 1
Part 1 completed.

Needed to fix the unittest a bit and then just code the function. This is such a
stupid exercise... -_-
Part 2 complete.

The odd numbered ones are a waste... >.<
Unit test for 3.

Can be extended in a moment...
Here's the crap version, aka part 3.
First 4 parts are done.
3rd part is done.

Silly assignment. Who would have thought this teacher would bore me in Python?
