Permutation of a given string using the inbuilt function in Python
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
ZYXIf you have any doubts regarding the program, please do mention them in the comment section.
