Itertools permutations

Itertool is a module provided by Python for creating iterators for efficient looping. It also provides various features or functions that work with iterators to produce complex iterators and help us to solve problems easily and efficiently in terms of time as well as memory.

permutation will receive two values

permutations(iterator,r)

• Iterator: will be the string or list that will be using as base for the permutation
• r: will be the length of the permutation item results

from itertools import permutations

a = "geEk"

p = permutatations(a,2)

for j in p:
    print(j)

Results:

('g', 'e') ('g', 'E') ('g', 'k') ('e', 'g') ('e', 'E') ('e', 'k') ('E', 'g') ('E', 'e') ('E', 'k') ('k', 'g') ('k', 'e') ('k', 'E')
