[Tutor] could someone please explain multiprocessing

[nathan tech]

Hi tutor List,


I hope everyone is keeping safe and doing well.

I was wondering if someone was able to explain the multiprocessing 
module to me.

I'm trying to get it to where my program would be able to do something like:

Hi parent, are you running?

Yes I am.

Great, here is a file for you.

Thanks child, you can close now and not launch a second instance.

okay, goodnight!


So far the way I've done this is through the socket module by having the 
first program listen on localhost, but this on some systems raises a 
windows security error. This obviously makes it rather suspicious!


I'm wondering how windows media player goes about it?


Thanks for any help you can offer.

Nathan
