1Multithreading is a model of program execution 
2that allows for multiple threads to be created 
3within a process, executing independently but 
4concurrently sharing process resources. 
5Depending on the hardware, threads can run 
6fully parallel if they are distributed to their own CPU core.

8	threading.Thread(target=func1).start()
9	threading.Thread(target=func2).start()
