I have noticed this behavior:

import itertools as iter

truc = iter.count(0)
trac = ["a",'b','c','d','e']
for i in range(3):
    zap = [x for x,y in zip(truc,trac)]
    print(zap)

which outputs

[0, 1, 2, 3, 4]
[6, 7, 8, 9, 10]
[12, 13, 14, 15, 16]

I don’t understand why the second list is not “`[5,6,7,8,9]“`. And the same goes for the third list, why it does not start at 11 ?
