Given a String. The task is to swap the first and the last character of the string.
Examples:
Input: GeeksForGeeks Output: seeksForGeekG Input: Python Output: nythoP
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 –
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 print(swapped_string) # Driver Code swap("GeeksforGeeks") swap("Python")
Output:
seeksforGeekG nythoP
