I wrote code like this:
main proc:
import socket_thread
#start 1000 connection
while i<1000:
    my_socket=socket_thread.socket_thread(i,host,port)
    my_socket.send(some_data)
    my_socket.recv()

socket_thread.py
class socket_thread:
    def __init__:
          self.soc_handle=socket.socket(socket.IF_INET,socket.DGRAM)
    def send(data):
          self.soc_handle.send(data)
    def recv():
          while 1:
 
input_list,output_list,exec_list=select.select([self.soc_handle],[],[],
2)
              data=input_list[0].recv(2048)
              print data

But it does not work as I hope. main proc can only initiate one thread
and then trapped by it, cannot get out.
I'm sure I missed something but I don't know. Thanks for any help.
