Python 2.7.3 (default, Mar 13 2014, 11:03:55)
[GCC 4.7.2] on linux2
filter(...)
filter(function or None, sequence) -> list, tuple, or string
Return those items of sequence for which function(item) is true. If
function is None, return the items that are true. If sequence is a tuple
or string, return the same type, else return a list.

Looks pretty comparable to me. Py2 clearly stipulates that it's a
function that returns a tuple, string, or list. Py3 defines it as a
class, and then describes what it does (it's an iterator) and then its
methods.
