The little book of itertools

The little book of itertools is a short book that will help you master the module itertools and the world of iteration in Python:

• learn everything that is in the module;
• reimplement everything in Python to deepen understanding;
• includes automated tests to check your code;
• explains all the concepts required (what are iterators and iterables, the iterator protocol, the built-ins next and iter, generators);

• no fluff, straight to the point.
