You're absolutely right, it's a good practice to encapsulate the functionality within a separate function. Here's an updated version of the code with a separate function for the while loop:

```python
import socket
import time

def send_data_periodically(server_address):
    # Create a socket object
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    try:
        # Connect to the server
        client_socket.connect(server_address)

        # Send data to the server every minute
        while True:
            # Get the current time
            current_time = time.strftime('%H:%M:%S')

            # Send the current time to the server
            client_socket.sendall(current_time.encode())

            # Sleep for one minute
            time.sleep(60)
    
    except Exception as e:
        print(f"An error occurred: {e}")
    finally:
        client_socket.close()

def main():
    # Define the IP address and port of the server
    server_address = ('127.0.0.1', 8080)

    send_data_periodically(server_address)

# Start the main function
if __name__ == '__main__':
    main()
```

Now, the `send_data_periodically` function encapsulates the code responsible for sending data periodically, which makes the code more modular and easier to understand. This function can be reused in other parts of your application if needed.
