udp服务端

from socket import *
ip_port = ('127.0.0.1',8080)
buffer_size = 1024

udp_server = socket(AF_INET,SOCK_DGRAM) #数据报
udp_server.bind(ip_port)     #找到端口

while True:
    data,addr = udp_server.recvfrom(buffer_size)
    print(data)
    udp_server.sendto(data.upper(),addr)

udp客户端

from socket import *
ip_port = ('127.0.0.1',8080)
buffer_size = 1024

udp_client = socket(AF_INET,SOCK_DGRAM) #数据报

while True:
    msg = input('==>:'.strip())
    udp_client.sendto(msg.encode('utf8'),ip_port)
    data,addr = udp_client.recvfrom(buffer_size)
    print(data.decode('utf8'))
