Not sure why Python’s list comprehensions not being generic might be such a great downside but just wanted to add that I personally think that they are perfectly fine just the way they are. For the context, I’ve been professionally writing Python code for 14 years now. I understand it’s not the perfect language but for quite average programmers like myself it does an excellent job of getting out of the way and of letting you focus just on the data, because that’s what programming is (or should be), i.e. managing and processing data.

Like I said, it’s not the perfect language, it does not have Erlang’s pattern matching nor Lisp’s insistence on thinking about almost everything in a recursive manner, but you can at least mentally try to incorporate those two philosophies into Python once you know about them (and once you know about other similar such great programming concepts).
