I aim to exercise Contract Driven Development. Write contract first, in python this would be in a doc-string of your stub. Then depending on your methodology either write your tests first followed by implementation (or vice-versa, depending on your preference). Then in the code document things that required you to run research (or more thinking power than usual).
