You could do many different things depending on your needs. You could write a daemon in python on one machine which waits for a python program on the other to command it to run a process. 

You could find out how to accomplish this using ssh and then just write a python script to execute that ssh command for you. 

Without more details it's hard too say what is more appropriate but I would suggest reading up on python subprocess module, ssh, and internet protocol and server modules in the standard library.
