"Like"? It *is* a form of co-operative multitasking.

The time machine strikes again!
Sounds like you want threads. Check out the threading module, but be
aware that many Python interpreters, including CPython (the most
commonly-used Python), have restrictions on when threads can switch
contexts. Chances are it'll work for you, but if it can't, you may
want to consider the multiprocessing module instead.
