Here is some heretical advice:

Do not use stuff like map and reduce unless they fit what you want to do 
perfectly, and "JustWorks" the first time.

You have a very clear idea of what you want to do, so why do you not just 
simply write something to do it?

something like this (untested):

def woofer(thefunc,thelist,thething):
	theanswers = []
	for x in thelist:
		theanswers.append(thefunc(x,thething))
	return theanswers

And the advantage is that you do not have to remember what map does...
