Python multithreading, How is it using multiple Cores?

multithreading

I am running a multithreaded application(Python2.7.3) in a Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz. I thought it would be using only one core but using the "top" command I see that the python processes are constantly changing the core no. Enabling "SHOW THREADS" in the top command shows diffrent thread processes working on different cores.

Can anyone please explain this? It is bothering me as I know from theory that multithreading is executed on a single core.
