Feel hard to learn the topic about " Parsing"

[Ofnuts]

So far I quite enjoyed learning Python from list and class to numpy and pandas. I have practiced ~80 algorithm type questions from leetcode and Hackrancker. They are nice web source for practice coding.

But the topic about parsing is always hard to learn for me, although the implementation of it is very useful. I feel it  is always easy to read someone's solution than doing the code by myself. I have searched and browsed several tutorial sources. They are understandable but still feel hard with the syntax such as (){}[]*+?. Too many symbol-like syntax. Hard to memorize.

So how do you learn the topic about parsing? What is the best way to learn it? Do you have any suggested online source to read?

Thanks,

It's not "parsing" it's "regular expressions" (which aren't specific to Python....). If you google for that you'll find plenty of online resources. But IMHO the best thing to do is to read the "Owl book". It takes you from noob to guru status in a couple of days.
