Python UDP-based sockets

1. UDP-based sockets

(1) UDP does not produce sticky packet phenomenon

(2) UDP is no link, first start which end will not error.

(3) The UPD is not connected, so multiple clients can communicate with the server at the same time.

2. Code examples

Service side:

 from Import *udp_server# Create a socket for a server udp_server.bind ('127.0.0.1 ' # binding a server socket  while True:    data,client_addr=udp_server.recvfrom (1024x768)  # Accept Message    Print (DATA,CLIENT_ADDR)    udp_server.sendto (Data.upper (), client_addr)  # Send Message 

Client:

 fromSocketImport*udp_client=socket (Af_inet,sock_dgram) whiletrue:msg=input ('>>:'). Strip () Udp_client.sendto (Msg.encode ('Utf-8'),('127.0.0.1', 8080)) Data,server_addr=udp_client.recvfrom (1024)    Print(Data.decode ('Utf-8'))
