How to receive and answer to socket asynchronously with Python?

Question

I'm working on a really basic "image streaming" server as a school subject, and I've done most of the work but I'm still stuck on the separation between data and control related sockets:

My structure is : TCPServer (my server, used as control socket) contains a dataSocket (only used to send images and initialized within my TCPServer object, when I receive a certain query)

When I'm sending data (images) through my dataSocket, I still need to see if the client sent a PAUSE or STOP request, but if I use python's self.request.recv(1024) the server awaits a response instead of continuing to send data (which is quite logical).

What should I do to prevent this behavior ? Should I launch my recv(1024) on a separate thread and run it at each loop (and check if I get any relevant data in between two iterations) ?

Twisted should do the trick! It handles asynchronous sockets in Python
