client端：

# import time
# import socket
# sk = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#
# while True:
# sk.connect((‘127.0.0.1‘,6667))
# print("hello")
# sk.sendall(bytes("hello","utf8"))
# time.sleep(2)
# break

server端：

# import time
# import socket
# sk = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
# sk.bind((‘127.0.0.1‘,6667))
# sk.listen(5)
# sk.setblocking(False)
# print (‘waiting client connection .......‘)
# while True:
# try:
#
# connection,address = sk.accept() # 进程主动轮询
# print("+++",address)
# client_messge = connection.recv(1024)
# print(str(client_messge,‘utf8‘))
# connection.close()
# except Exception as e:
# print (e)
# time.sleep(4)
