Actually I was just looking at Python 2.5 docs since you mentioned this. http://www.python.org/dev/doc/devel/whatsnew/node3.html It says min() and max() will gain a key function parameter, and sort() gained one in Python 2.4 (news to me). And they do indeed default to the identity in all 3 cases, so this seems very inconsistent. If one of them has it, and sort gained the argument even in Python 2.4 with generator expressions, then they all should have it. > any(x >= 42 for x in data) Not to belabor the point, but in the example on that page, max(L, key=len) could be written max(len(x) for x in L). Now I know why Guido said he didn't want a PEP for this... such a trivial thing can produce a lot of opinions. : ) Roose -- http://mail.python.org/mailman/listinfo/python-list
