15. All Permutations of n Objects

Write a Python program to generate all possible permutations of n different objects.

Sample Solution:

Python Code:

import itertools
def permutations_all(l):
    for values in itertools.permutations(l):
        print(values)

permutations_all([1])
print("\n")
permutations_all([1,2])
print("\n")
permutations_all([1,2,3])

Sample Output:

(1,)


(1, 2)
(2, 1)


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