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))
