You have some starting tools in the python lesson here on SL.
I suggest you to learn those, and once you did, try to answer assignments where strings are involved in the assignments section. You'll sometimes need to google for new tools and the web forest is full of them : )
Practice and practice ...

I made a regex quiz a while back if you want to check it out 😊 And also this password strength checker code use some regex.
I also highly recommend this site https://regexr.com . I use it when making complicated regex patterns, it's a really good tool.

Check out the comparisons in both Part 1 and Part 2 of this link:
