In Python 3 reduce was removed and you'd have to use functools.reduce. Similarly lambda functions are a bit of a mistake, in Guido's opinion, as well as his preference to use list comprehensions over filter(). I don't expect to see more functional programming constructs anytime soon in Python. That being said, list comprehensions work quite well in Haskell, Python, etc.
