Why it is giving ouput as [] ? Where as range(0,11,1) is giving desired output?

Question

rom itertools import product, permutations

letters = ("A", "B")
print(list(product(letters, range(0,11,-1))))

Answer 1

You have written -1 in range as step. Just clear it.

Answer 2

Because the route from 0 to 10 is straight. You can write range (10, -1, -1)

Answer 3

Why didn't it print those in reverse oder?

Answer 4

Thank you 😊
