Practice your Python Pandas data science skills with problems on StrataScratch! https://stratascratch.com/?via=keith In this video we go through all the fundamentals of using regular expressions (regexes) to match patterns in programming. In this video we cover the following: Character Sets [a-zA-Z0-9] Quantifiers *, +, ?, {3,5} Metacharacters ^ . | $ Character Classes \b \s \w \d Groups Lookahead & Lookbehind assertions and more! There is a detailed timeline down below. In a future video we will apply what we learn in this one to the Python programming language (re library) -- subscribe to not miss that! Resources!
