Get process Id of a function, not process of what is running my Django server

Question

I am currently using psutil to do...

p = psutil.Process(pid)
p.kill()

...In an attempt to kill the process of one function (that I thought I was getting the pid of with):

os.getpid()

...Though this kills my entire manage.py runserver command and I have to restart the server.

Does anyone know what I can do here?

Functions do not have a process ID independent of the VM. Your question is meaningless.

Perhaps my last sentence can negate your last sentence if you actually understand what I am trying to do – Mike Johnson Jr Dec 05 '16 at 08:47

There is no such thing as "the process of one function". All functions run in the same process. – Ignacio Vazquez-Abrams Dec 05 '16 at 08:49
What, then, is the purpose of the multiprocessing package that I've just found? https://docs.python.org/3/library/multiprocessing.html – Mike Johnson Jr Dec 05 '16 at 08:54

It's certainly not to make any arbitrary Python program use multiple processes... – Ignacio Vazquez-Abrams Dec 05 '16 at 08:55

@MikeJohnsonJr - Did you read the answer to that question? " call the library "... it doesn't say anything about terminating a function. – Sayse Dec 05 '16 at 09:27
I've answered my question. Thank you both for your help – Mike Johnson Jr Dec 05 '16 at 09:39

As Ignacio said, my question didn't make sense: "Functions do not have a process ID independent of the VM"

Though to answer the essence of my question: "how can i stop the execution of a function (infinite while loop) from outside of that function?"

We check a flag, e.g. a value set in a database. Helped by a kind stranger in #python in freenode
