本文实例为大家分享了python创建tcp服务端和客户端的具体代码，供大家参考，具体内容如下

1.服务端server

from socket import *from time import ctimeHOST = ''PORT = 9999BUFSIZ = 1024ADDR = (HOST, PORT)tcpSerSock = socket(AF_INET, SOCK_STREAM)  #创建套接字tcpSerSock.bind(ADDR)  #绑定IP和端口tcpSerSock.listen(5)  #监听端口，最多5人排队while True:  print('waiting for connection...')  tcpCliSock, addr = tcpSerSock.accept()  #建立连接  print('...connected from:', addr)  while True:    data = tcpCliSock.recv(BUFSIZ)    if not data:      break    content = '[%s] %s' % (bytes(ctime(), "utf-8"), data)    print(data)    print(type(content))    tcpCliSock.send(content.encode("utf-8"))  tcpCliSock.close()tcpSerSock.close() 

2.客户端client

from socket import *HOST = '127.0.0.1' # or 'localhost'PORT = 9999BUFSIZ = 1024ADDR = (HOST, PORT)tcpCliSock = socket(AF_INET, SOCK_STREAM)tcpCliSock.connect(ADDR)while True:  data = input('> ')  if not data:    break  tcpCliSock.send(data.encode("utf-8"))  data = tcpCliSock.recv(BUFSIZ)  if not data:    break  print(data.decode("utf-8"))tcpCliSock.close()

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
