An example might help. Back in the old days, before Python had a sum()
function, the easiest way to add up a list of numbers was to use reduce
and a small function to add two numbers:
def add(x, y):
return x+y
total = filter(add, [2, 4, 5, 9, 1])
Arggggh! Of course, I meant *reduce* in that example, not filter. Sorry
for any confusion!
