This article "how to use Python to achieve a multitasking version of udp chat" article knowledge point most people do not understand, so Xiaobian summarized the following content for everyone, detailed content, clear steps, has a certain reference value, I hope you can read this article to gain something, let's take a look at this article "how to use Python to achieve a multitasking version of udp chat" article bar.

I. Case examples II. Case descriptions

Write a program with 2 threads.

Thread 1 is used to receive data and then display it.

Thread 2 is used to detect keyboard data and then send data through udp.

import socketimport threadingdef send_msg(udp_socket): """Get keyboard data and send it to the other party""" while True: # 1. Enter data from keyboard msg = input("\nPlease enter data to send:") # 2. Enter the IP address of the other party dest_ip = input("\n Please enter the IP address of the other party:") # 3. Enter the port of the other party dest_port = int(input("\n Please enter the port of the other party:")) # 4. transmit data udp_socket.sendto(msg.encode("utf-8"), (dest_ip, dest_port))def recv_msg(udp_socket): """Receive data and display""" while True: # 1. receive data recv_msg = udp_socket.recvfrom(1024) # 2. decoding recv_ip = recv_msg[1] recv_msg = recv_msg[0].decode("utf-8") # 3. Display received data print(">>>%s:%s" % (str(recv_ip), recv_msg))def main(): # 1. create a socket udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # 2. Binding local information udp_socket.bind(("", 7890)) # 3. Create a child thread to receive data t = threading.Thread(target=recv_msg, args=(udp_socket,)) t.start() # 4. Let the main thread detect keyboard data and send it send_msg(udp_socket)if __name__ == "__main__": main() The above is about "how to use Python to achieve a multitasking version of udp chat" The content of this article, I believe everyone has a certain understanding, I hope the content shared by Xiaobian is helpful to everyone, if you want to know more related knowledge content, please pay attention to the industry information channel.
