I've gone and done 20 problems on Project Euler, and learned a little, but it didn't seem like the fastest way to learn. Some of the problems took me awhile, but mostly they could be done with things I already knew. There was just one that I had to resort to Googling how to do, which led to learning a bit more about Python's max command. But maybe I should take most of Project Euler seeming relatively easy as encouragement?
