Using the itertools module specifically the permutation:

from itertools import permutations

print(list(permutations([1, 2, 3])))

Python is easy because lots of library are available. go through the documentation for source code https://docs.python.org/3/library/itertools.html#itertools.permutations

import itertools
a=[1,2,3]
for k in itertools.permutations(a, len(a)):
    print(k)

Solution

(1, 2, 3)
(1, 3, 2)
(2, 1, 3)
(2, 3, 1)
(3, 1, 2)
(3, 2, 1)
