Congrats for this post. For me, is quite difficult to make some personal project for learn something new. One thing that works for me is make some little goals to achieve a main goal. When I realize the evolution of my learning, I stay more motivated than I would be if I've looking only to the main target.

Very nice post!! As a Java programmer I was very confusing about Phyton's yield behavior. In Java we have a yied method within a Thead class and it's tells a thread scheduler that if it wants to pause current thread it seems to be a good time to pause current execution. Introducing a generator function concept, it seems more clearly to me how it works on runtime. Great post!
