Python Sort String: Quick and Easy Guide

Sort a String using sorted() and join() functions

Python provides a number of built-in functions for working with strings, including the sorted() and join() functions.

The sorted() function can be used to sort a string alphabetically, while the join() function can be used to join together a list of strings into a single string. Together, these functions can be used to sort a string alphabetically.

Code example - Sort string in ascending order

input_str = 'programming'

result_str = ''.join(sorted(input_str))

print(f'The original string is: {input_str}')
print(f'The sorted string is: {result_str}')

Output

The original string is: programming
The sorted string is: aggimmnoprr

1. In the above code example, we have created a string variable called input_str and assigned the string 'programming' to it.
2. Then we created a string variable called result_str and assigned to it the result of running the string method sorted on input_str. sorted returns a list of the characters in input_str in alphabetical order, which is then joined into a string using the join() method.
   
3. Then we print the original string and the sorted string to the console.

Code example - Sort string in descending order

input_str = 'programming'

result_str = ''.join(sorted(input_str, reverse=True))

print(f'The original string is: {input_str}')
print(f'The sorted string is: {result_str}')

Output

The original string is: programming
The sorted string is: rrponmmigga

In the above code example, we are sorting the string in descending order. We are using reverse=True in the sorted() function to do that.
