Hi

This is IMDB dataset from kaggle and im reading someone's code

im very confuse by this. What is regular expression?

What is compile and findall doing? (a typical element in the "runtime" col is, for example, 142 min)

What is going on when it comes to appending. it makes no sense. please explain clearly
