I suggest writing some unit tests[1]. I use py.test[2] and
pytest-qt[3] which makes this a lot easier.

You'll get more familiar with Python, with the application you're
porting, and - most importantly - if you have good test coverage
([4] helps), you'll instantly know what works and what doesn't.

Also, seeing the number of successful tests go up while you're working
is satisfying! :)
