Ironically, I didn't understand Python's list comprehensions until I learned about Haskell's version (which is the original source of Python's), along with the explanation that Haskell's list comprehensions are taken straight from mathematics. Indeed, Haskell's version are almost ASCII-art mathematical set notations. Even now, I still like Haskell's [fn(x) | x <- myList, x < 5] over Python's equivalent [fn(x) for x in myList if x < 5] Of course, I'm a mathematician, so that probably explains everything about my convoluted path of understanding these things, and my preferences to this day. :-)
