Permutation of a given string using the inbuilt function in Python

Python Server Side Programming Programming

In this tutorial, we are going to find the permutation of a string using the inbuilt function of Python called permutations. The method permutations is present in the itertools module.

Procedure To Find The Permutation Of A String

Import the itertools module.
Initialize the string.
Use the itertools.permutations method to find the permutation of the string.
In the third step, the method returns an object and convert it into a list.
- List contains a permutation of string as tuples.

Example

Let's see the program.

## importing the module
import itertools
## initializing a string
string = "XYZ"
## itertools.permutations method
permutaion_list = list(itertools.permutations(string))
## printing the obj in list
print("-----------Permutations Of String In Tuples----------------")
print(permutaion_list)
## converting the tuples to string using 'join' method
print("-------------Permutations In String Format-----------------")
for tup in permutaion_list:
   print("".join(tup))

Output

If you run the above program, you will get the following result.

-----------Permutations Of String In Tuples----------------
[('X', 'Y', 'Z'), ('X', 'Z', 'Y'), ('Y', 'X', 'Z'), ('Y', 'Z', 'X'), ('Z', 'X', 'Y'), ('Z', 'Y', 'X')]
-------------Permutations In String Format-----------------
XYZ
XZY
YXZ
YZX
ZXY
ZYX

If you have any doubts regarding the program, please do mention them in the comment section.
