[Python]socket简易服务端客户端通信

服务端:

import socketserver = socket.socket()server.bind(('localhost', 6666))server.listen()while True:    print('waiting...')    coon,addr = server.accept()    print('coming!',addr)    while True:        rec = coon.recv(1024)        if len(rec)<=0:            print(addr,'lost...')            break        print('rec:',rec)        coon.send(rec.upper())server.close()

客户端:

import socketclient= socket.socket()client.connect(('localhost',6666))while 1:    try:        send = input('>>:')        client.send(bytes(send,encoding = 'utf-8'))        rec = client.recv(1024)        print(rec)    except KeyboardInterrupt:        exit()client.close()
