Forgive me for asking, but how could that book help me down the road? Scheme seems so obscure to me. I was at the bookstore and checked it out, and was mildly intimidated by it, although the illustrations were cute.
I ended up purchasing Practical Programming. Thank you all for your recommendations, some I have saved into my reading list.
It's not really meant to just teach you scheme. Scheme by itself is incredibly minimalist and simple. The exercises are more logic/math-based puzzles. Here's a list of the exercises themselves:
TLS will break your mind in the most delicious way. I can't recommend it enough. As for practicality, I think that the world is trending in directions that make becoming comfortable with recursion more important.
It'll make you a better Python programmer for sure.
