6. Reverse Bytes Object

Write a Python function to reverse a given bytes object.

Sample Solution:

Code:

def reverse_bytes(byte_obj):
    reversed_bytes = byte_obj[::-1]
    return reversed_bytes

def main():
    try:
        original_bytes = b"Python Exercises!"
        
        reversed_result = reverse_bytes(original_bytes)
        
        print("Original Bytes:", original_bytes)
        print("Reversed Bytes:", reversed_result)
        print("Reversed String:", reversed_result.decode("utf-8"))
    except Exception as e:
        print("An error occurred:", e)

if __name__ == "__main__":
    main()

Output:

Original Bytes: b'Python Exercises!'
Reversed Bytes: b'!sesicrexE nohtyP'
Reversed String: !sesicrexE nohtyP

In the exercise above, the "reverse_bytes()" function takes a bytes object as input and reverses it using slicing with a step of -1. In the "main()" function, a sample bytes object is provided and the reversed bytes and the reversed string are printed.

Flowchart:

For more Practice: Solve these Related Problems:

• Write a Python function to reverse a given bytes object and then compare the reversed result with slicing.
• Write a Python program to take a bytes object, reverse its order, and print both the original and reversed bytes.
• Write a Python script to implement a manual reversal of a bytes object using a loop and then validate it with Python’s slicing technique.
• Write a Python function that accepts a bytes object, reverses it, and then converts it to a hexadecimal string for display.
