In this tutorial, we will learn how to compute all the permutations of a string in Python. We will cover the basic concept of permutations and use the itertools library to generate all possible permutations of a given string.
Permutations are all possible arrangements of a set of elements. For a given string, permutations are all possible ways to rearrange its characters.
The syntax to compute all the permutations of a string in Python is:
from itertools import permutations
def compute_permutations(s):
return [''.join(p) for p in permutations(s)]
We can create a function to compute all permutations of a given string using the itertools library.
For example,
permutations
function from the itertools
library.compute_permutations
that takes one parameter s
.permutations
function to generate all possible permutations of the string.from itertools import permutations
def compute_permutations(s):
return [''.join(p) for p in permutations(s)]
# Sample string
sample_string = 'abc'
# Compute all permutations of the sample string
result = compute_permutations(sample_string)
# Print the result
print('Permutations of', sample_string, 'are:', result)
Permutations of abc are: ['abc', 'acb', 'bac', 'bca', 'cab', 'cba']
