python如何创建TCP服务端和客户端

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 ctime

host = ''
port = 9999
bufsiz = 1024
addr = (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 = 9999
bufsiz = 1024
addr = (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()
