新建server.py写入代码如下

import socketHOST="127.0.0.1"PORT=6666s=socket.socket()s.bind((HOST,PORT))  s.listen(1)back="ok"while 1:	conn,addr=s.accept()  	print('Connected by'+str(addr))	while 1 :		data=conn.recv(1024)		print(str(data))		conn.sendall(bytes(back, encoding = "utf8"))conn.close()

新建Client.py

import socketHOST='127.0.0.1'PORT=6666s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)s.connect((HOST,PORT))       while 1:	cmd=input("Please input cmd:") 	s.sendall( bytes(cmd, encoding = "utf8")  )     	data=s.recv(1024)    	print (str(data))      s.close()
