Python Reverse String

Here is a simple function that takes a string as an argument and returns the reversed string:

def reverse_string(string):
    # Initialize an empty string
    reversed_string = ""
    # Iterate over the string in reverse order
    for i in range(len(string)-1, -1, -1):
        # Append each character to the reversed string
        reversed_string += string[i]
    # Return the reversed string
    return reversed_string

print(reverse_string("hello")) # Output: "olleh"
print(reverse_string("world")) # Output: "dlrow"
print(reverse_string("python")) # Output: "nohtyp"

This function uses a for loop to iterate over the string in reverse order and appends each character to a new string. The reversed string is then returned.

Alternatively, you could use the join() and slicing method to reverse the string:

def reverse_string(string):
    return "".join(string[i] for i in range(len(string)-1, -1, -1))

print(reverse_string("hello")) # Output: "olleh"
print(reverse_string("world")) # Output: "dlrow"
print(reverse_string("python")) # Output: "nohtyp"

This method uses a list comprehension to iterate over the string in reverse order and creates a new string by joining each character. The reversed string is then returned.

You can use either of these methods to reverse a string in Python. Choose the one that best suits your needs and use it in your code.
