10. Bytearray to Bytes Conversion

Write a Python function that converts a bytearray to a bytes object.

Sample Solution:

Code:

def bytearray_to_bytes(bytearray_obj):
    bytes_obj = bytes(bytearray_obj)
    return bytes_obj

def main():
    try:
        original_bytearray = bytearray([12, 51, 10, 15, 95, 102, 132, 117])
        
        bytes_result = bytearray_to_bytes(original_bytearray)
        
        print("Original Bytearray:", original_bytearray)
        print("Bytes Object:", bytes_result)
        print("Decoded String:", bytes_result.decode("utf-8"))
    except Exception as e:
        print("An error occurred:", e)

if __name__ == "__main__":
    main()

Output:

Original Bytearray: bytearray(b'\x0c3\n\x0f_f\x84u')
Bytes Object: b'\x0c3\n\x0f_f\x84u'
An * error occurred: 'utf-8' codec can't decode byte 0x84 in position 6: invalid start byte

In the above exercise, the "bytearray_to_bytes()" function takes a bytearray as input and converts it into a bytes object using the bytes() constructor. In the "main()" function, a sample bytearray is provided, converted to a bytes object, and the decoded string is printed.

For more Practice: Solve these Related Problems:

• Write a Python program to convert a bytearray to a bytes object and then print both objects to compare their types.
• Write a Python script to create a bytearray from user input, convert it to bytes, and then display the length of each.
• Write a Python function to take a bytearray, perform modifications on it, then convert the final result to a bytes object and print it.
• Write a Python program to transform a bytearray to bytes and then use that bytes object in a function that requires immutable data.
