# coding:utf-8                                                                   import socket   def make_socks(sock_num):     socks = []     for i in range(sock_num):         tmp_sock = socket.socket()         tmp_sock.connect(("127.0.0.1",1234))         socks.append(tmp_sock)           return socks  if __name__ == "__main__":     make_socks(5)

如上例代码中，有listen(3)，这个3是指什么，是指，这个socket只能与3个socket建立链接吗，为什么我用上面的代码可以创建大于3个的tcp连接却没报错，理论上大于3个连接应该报错的
