from multiprocessing import Process, Pipe # define the function for the child process def child(conn): # receive data from the parent process msg = conn.recv() print("Child received message: ", msg) # create a pipe for communication parent_conn, child_conn = Pipe() # create the child process p = Process(target=child, args=(child_conn,)) # start the child process p.start() # send data to the child process parent_conn.send("Hello from parent process!") # wait for the child process to finish p.join()In this example, a parent process creates a pipe for communication with a child process and starts the child process. The parent process sends a message to the child process through the pipe using the send() method on the parent_conn object, and the child process receives the message using the recv() method on the child_conn object. The multiprocessing library in Python provides the Pipe() function for inter-process communication.
