I have plenty of projects to work on in my spare time…but recently, I’ve been blowing them all off and playing with the Python Challenge instead. It’s a set of riddles that can be solved with a little Python code, a little creativity, and for me, lots of visits to the forums for hints. The riddles are surprisingly elegant and well-designed. Often you’ll get as little as a picture and a couple words to start off with, but the riddle will slowly unfold as you track down leads. As a scavenger hunt for the geek set, it’s a lot of fun.
