Regular expression (also abbreviated to regex) really is a powertool any programmer should know. It was and is one of the things I most liked learning, as it provides you with immediate, godlike powers that can speed up your (data science) workflow tenfold.
I’ve covered many regex related topics on this blog already, but thought I’d combine them and others in a nice curated overview — for myself, and for you of course, to use.
If you have any materials you liked, but are missing, please let me know!
