Today’s Code Snippet of the Day will reverse a string in Python and show the text (string) in reversed form. Let’s illustrate this with a simple “hello world” program, In the example the text placed inside the string will appear as “!dlrow ,olleH”.
def reverse_string(string): """Reverses a string. Args: string: A string. Returns: A string with the characters in reverse order. """ reversed_string = "" for i in range(len(string) - 1, -1, -1): reversed_string += string[i] return reversed_string # Example usage: string = "Hello, world!" reversed_string = reverse_string(string) print(reversed_string)
We can use the reverse string feature in a variety of tasks such as text processing, data analysis, and cryptography. It is also a good example of a simple but useful function that can be written in Python.
