Like dcat said in IRC, you'll learn the most by finding things written in Python in Ruby (either on github or elsewhere) and "dissecting" it. This is the primary way I have learned to program, and it's partly because of my interest in ricing. Being able to look through source code and completely understand everything that is going on is a skill that you can develop over time and will definitely make you a better programmer. Customize code to fit your needs, play with it, break it, understand how you broke it, etc. It will all help. Good luck!
