I always recommend you to everyone who wants to know python or even if they know already. I have learned a lot, but I always watch your videos to keep learning, even if I forgot some topics that I don't want to pass over. By another hand this the best video tutorial that I ever have seen about Regular Expressions. Thank you very much Corey.

    I commented on the other regex video you did, but last night and today I watched this video and again took really detailed notes. Today I was working on something where I had to strip off a bunch of characters and I thought, “you know what, I think I can just write a regular expression to do this instead of .strip().etcetc” So I wrote a pattern to match my string with re.compile(), then used var.sub(r’\groupnumberhere’), appended to a new list, and accomplished exactly what I needed to quickly and easily instead of having to .strip(), etc. I used to be so intimidated by this stuff; really can’t thank you enough!

    I'm just reading about regex on Automate the Boring Stuff and this video has really helped make things easier to understand. Corey does a great job of showing why you might want to do something as well as how to then do it. Really good stuff
