Converting Python memory view to bytes: Function and example

Python Memory Views Data Type: Exercise-2 with Solution

Write a Python function that takes a memory view and converts it to a bytes object.

Sample Solution:

Code:

def memoryview_to_bytes(mem_view):
    try:
        # Convert memory view to bytes using bytes()
        bytes_data = bytes(mem_view)
        return bytes_data
    except Exception as e:
        print("An error occurred:", e)
        return None

def main():
    try:
        data = b"Python Exercises!"
        mem_view = memoryview(data)
        print("Memory views: ",mem_view)
        # Convert memory view to bytes
        bytes_data = memoryview_to_bytes(mem_view)
        
        if bytes_data is not None:
            print("Bytes Object:", bytes_data)
    except Exception as e:
        print("An error occurred:", e)

if __name__ == "__main__":
    main()

Output:

Memory views:  <memory at 0x00000266DBB4E108>
Bytes Object: b'Python Exercises!'

The above exercise demonstrates how to convert a memory view to a bytes object using the bytes() constructor.
