Yes, list comprehensions are the bomb once you get a handle on them. I remember reading through one of my first Python books and my eyes just glazed over when covering that topic (similar to what used to happen to me back in school in maths, actually... I wonder if I have dyscalculia...). It was only when I saw a real simple example in someone else's code that was clearly commented that it clicked with me.
