My answer to What are the best resources for learning regular expressions? on Quora
The O’Reilly book on Regular Expressions is absolutely superb. It will help you build a much deeper understanding if how they actually work than any online tutorial I’ve seen.
Chapter 3 of “Text Processing in Python” is excellent too, and is available for free online:
