Python Regular Expressions - PDF

Python + Regex? Many of you do not find this combination easy, which partly happens because of the Python's obfuscated regex documentation too! In this course, to make your life easy, we have used some real-world examples. The goals are to teach you how to use the Python regular expressions (re) module and relevant functions by running interactive examples and challenge you with coding exercises and quizzes. 

This is PDF book should be pretty quick and easy to complete. This  should get you going with Python Regex in less than 30mins. More information.
