这篇文章主要为大家详细介绍了python实现单线程多任务非阻塞TCP服务端的相关资料，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了python实现单线程多任务非阻塞TCP 服务端的具体代码，供大家参考，具体内容如下

									# coding:utf-8

									from socket import *

									# 1.创建服务器socket

									sock = socket(AF_INET, SOCK_STREAM)

									# 2.绑定主机和端口

									addr = ('', 7788) #

									sock.bind(addr)

									# 3. 设置最大监听数目，并发

									sock.listen(10)

									# 4. 设置成非阻塞

									sock.setblocking(False)

									# 保存客户端socket

									clientAddrList = []

									# print(sock.)

									while 1:

									  try:

									    clientSocket, clientAddr = sock.accept()

									  except:

									    pass

									  else:

									    print("一个新客户端到来：%s" % str(clientAddr))

									    clientSocket.setblocking(False)

									    clientAddrList.append((clientSocket, clientAddr))

									  for clientSocket, clientAddr in clientAddrList:

									    try:

									      recvData = clientSocket.recv(1024)

									    except:

									      pass

									    else:

									      if len(recvData) > 0:

									        print("%s:%s" % (str(clientAddr), recvData))

									      else:

									        clientSocket.close()

									        clientAddrList.remove((clientSocket, clientAddr))

									        print("%s 已经下线" % str(clientAddr))
