LAMBDA IS IT USELESS?

It is like using nameless intermediary results.

You might expand your code into

aux = lambda x,y: x*y
f = reduce(aux,n)

and then replace my first line with the equivalent pair of lines

def aux(x,y):
    return x*y

The whole thing is similar to writing

f = a*b*c

instead of

aux = a*b
f = aux*c

, just with other types (functions instead of numbers).
