Greetings,
Given this snippet
from itertools import *
import operator
x = [1, 2, 3] # [0, 1, 2, 3, ..., 10]
y = accumulate(x, operator.mul)
print(list(y))
why does x = list(range(5)) produces only zeros?
That is an easy one.
By default, range() starts from 0. Anything multiplied by 0 equals 0. So
you can multiply as many numbers as you like, if the first one is 0, the
rest will also be 0.
