Python のマルチプロセッシング ライブラリはどのようにして双方向のプロセス間通信を促進できるのでしょうか?

<code class="python">from multiprocessing.connection import Listener

# Define the server address
address = ('localhost', 6000)

# Create a listener with a secret password for authentication
listener = Listener(address, authkey=b'secret password')

# Accept incoming connections
conn = listener.accept()
print('Connection accepted from', listener.last_accepted)

# Process incoming messages
while True:
    msg = conn.recv()
    # Handle the message
    if msg == 'close':
        # End the communication
        conn.close()
        break
listener.close()</code>

<code class="python">from multiprocessing.connection import Client

# Specify the server address
address = ('localhost', 6000)

# Connect to the server using the secret password
conn = Client(address, authkey=b'secret password')

# Send commands to the server
conn.send('close')
# Send arbitrary objects as well
# conn.send(['a', 2.5, None, int, sum])

# Close the connection
conn.close()</code>
