python implements single threaded multitask non blocking TCP server

This article shares the specific code of python's implementation of single-threaded multitask non-blocking TCP server for your reference. The specific content is as follows

# coding:utf-8
from socket import *

# 1. Create server socket
sock = socket(AF_INET, SOCK_STREAM)

# 2. Bind host and port 
addr = ('', 7788) #
sock.bind(addr)

# 3.  Sets the maximum number of listens and concurrency 
sock.listen(10)

# 4.  Set to non-blocking 
sock.setblocking(False)
#  Save client socket
clientAddrList = []
# print(sock.)

while 1:
  try:
    clientSocket, clientAddr = sock.accept()
  except:
    pass
  else:
    print("1 A new client arrives: %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  Has been rolled off the production line " % str(clientAddr))
