zClient.py

# coding=utf-8
import socket

HOST = '192.168.4.102'  #服务器主机IP地址
PORT = 50007    #服务端主机端口号
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect((HOST,PORT))    #建立连接
while True:
    c =input('Input the content you want to send:')
    s.sendall(c.encode())   #发送数据
    data = s.recv(1024) #从客户端接受数据
    data = data.decode()
    print('Received:',data)
    if c.lower() == 'bye':
        break
s.close()   #关闭连接

先运行zServer.py再运行zClinet.py
