udp通信

服务端：

import socket

sk = socket.socket(type=socket.SOCK_DGRAM)
sk.bind(("127.0.0.1", 8080))

while True:
    msg, addr = sk.recvfrom(1024)
    print(msg.decode("utf-8"))
    send_msg = input(">>>")
    sk.sendto(send_msg.encode("utf-8"), addr)

客户端：

import socket

sk = socket.socket(type=socket.SOCK_DGRAM)
server = ("127.0.0.1", 8080)

while True:
    send_msg = input(">>>")
    if msg.upper() == "Q":
        break
    sk.sendto(send_msg.encode("utf-8"), server)
    msg = sk.recv(1024).decode("utf-8")
    if msg.upper() == "Q":
        break
    print(msg)
