Same result, different composition. Personally, given Guido's
predisposition to eliminating reduce() in Python 3000 [1], I'd be
avoiding using reduce in new code.
A python implementation of reduce:
NOT_GIVEN="(*piuhuI&*uyobJH!ikuoi1p9e;mks c0p[p"
def reduce_(f,s,i=NOT_GIVEN):
it=iter(s)
if i == NOT_GIVEN:
try:
result = it.next()
except StopIteration:
raise TypeError, "reduce() of empty sequence with no initial value"
else:
result = i
for i in it:
result = f(result,i)
return result
