Have you ever realized there are tons of build in libraries come with Python? Have you realized that you only happen to know very few of them? Have you ever wanted to learn more about the rest but it turned out that the documentation is meaningless because you are a “handy” people because you want to see examples?

Doug has a website called pymotw.com/2 where you can find the code examples for rarely used libraries, like this one about shlex (simple lexical analysis).

If you feel better holding a book in your hand, here is a book that you can buy.
