Python Tutorial Was: Guido's regrets: filter and map

[Lulu of the Lotus-Eaters]

||And it doesn't replace reduce at all -- we've yet to see a construct
||proposed to do that (aside from writing it out as an explicit loop).

Actually... here's an... ummm... "improved" version:

reduce = lambda func, seq, init=None:\
         [(l.append(func(l[i],seq[i])),l[-1])
                         for l in [[init or seq[0]]]
                         for i in range(len(seq))][-1][1]

Yours, Lulu...
