Write a function to reverse a string in Python

Certainly! You can reverse a string in Python using several approaches. Here are a few methods to achieve this:

1. Using slicing: Python strings support slicing, and you can reverse a string s using the slicing technique s[::-1].

def reverse_string(s):
    return s[::-1]

2. Using a loop: Iterate over the string in reverse order and build the reversed string character by character.

def reverse_string(s):
    reversed_str = ''
    for char in s:
        reversed_str = char + reversed_str
    return reversed_str

3. Using join and reversed: Convert the string into a list of characters, reverse the list, and join it back into a string.

def reverse_string(s):
    return ''.join(reversed(s))

All of these functions will reverse a given string s. Here's how you can use them:

# Example usage:
input_str = "Hello, World!"
print(reverse_string(input_str))  # Output: "!dlroW ,olleH"

Choose the method that suits your preference or fits best with the rest of your code!
