Correction: I guess the link I provided above is old news... In the more recent Python 3000 FAQ, GvR says:
Q. If you're killing reduce(), why are you keeping map() and filter()? A. I'm not killing reduce() because I hate functional programming; I'm killing it because almost all code using reduce() is less readable than the same thing written out using a for loop and an accumulator variable. On the other hand, map() and filter() are often useful and when used with a pre-existing function (e.g. a built-in) they are clearer than a list comprehension or generator expression. (Don't use these with a lambda though; then a list comprehension is clearer and faster.) So it seems only reduce will be eliminated. Luis -- http://mail.python.org/mailman/listinfo/python-list
