&＃39;a socket example which send echo message to server.&＃39;

import socket

s &＃61; socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.connect((&＃39;127.0.0.1&＃39;, 9999))

print(s.recv(1024))

for data in [&＃39;Michael&＃39;, &＃39;Tracy&＃39;, &＃39;Sarah&＃39;]:

s.send(bytes(data, encoding&＃61;&＃39;utf-8&＃39;))

print(s.recv(1024))

s.send(bytes(&＃39;exit&＃39;, encoding&＃61;&＃39;utf-8&＃39;))

s.close()

运行结果如图&＃xff1a;
