How not to wait until the end of a function call in Python?

Question

So I have a function like this:

import time

def f(a):
   if(a>1):
      time.sleep(3600)

f()
#код выполняется дальше

The function I gave as an example of a function that is very long. How to call a function and not wait for the end of the process? I would like to hear the short answer, not a recommendation of the form "Read a three-volume, Lutz and all will understand"

Just bear in mind that Python has a global lock, and this paralleling is very conditional.
In General, all depends on tasks. If you write something to the network, it is best to take tornado /asyncio or celery
