In learn more python 3 the hard way in ex7 grep command. Do I need to read the book on regular expression or just documentation of re module is sufficient?

I want to know where are the companion videos of learn more python 3 the hard way.

So, I’m going to give you some quick advice for the book:

Slow down.

I can already tell you’re kind of skipping over things and bouncing around and rushing. Take your time. For example, there’s a page in the beginning of the book, right after the preface that says how to do this, but you missed it. Slow down, read everything, watch all the videos, do your code in tiny chunks, run it all the time, and you’ll do a lot better.
