from itertools import permutations

my_list = [1, 2, 3]

list_of_permutations = permutations(my_list)
for permutation in list_of_permutations:
    print(permutation)

Running Result:

from itertools import permutations

list_of_permutations = permutations(my_list)
cnt = 0
for permutation in list_of_permutations:
    cnt += 1
print(len(my_list), cnt)

Running Result:
