Python string is immutable which means we cannot modify it directly. But Python has string slicing which makes it very easier to perform string operations and make modifications. Follow the below steps to swap characters –

  1. We initialize a variable start, which stores the first character of the string (string[0])
  2. We initialize another variable end that stores the last character (string[-1])
  3. Then we will use string slicing, string[1:-1], this will access all the characters from the 2nd position excluding the last character.
  4. Then we add these three as required forming a new string that has the first and last characters of the original string swapped. And then we will print it.

Below is the implementation.


def swap(string):
    # storing the first character
    start = string[0]
    # storing the last character
    end = string[-1]
    swapped_string = end + string[1:-1] + start
# Driver Code
