[Python] Pausing, unpausing, and stopping threads in python

I am trying to make a program that has equivalents for another module's code.

The module has it's own thread class, with the commands 'stop', and 'sleep_for'

For example, using this module, you could do this:

from fancyModule import *
import time

def yell():
while True:
print('HI!!!')

mythread = Thread('HI!!!')
time.sleep(3)
mythread.stop()


For my problem, I am making my own file, to be imported instead of the fancy one.

I can use threading, multiprocessing, asyncio, or just about anything. The problem that I am running into, is that the users function can be just about anything, so I can't use events or flags. Is there anything I can do? Maybe by stopping the thread/process from the function? Here is what I have tried:

class Thread:
def __init__(self, callback, *arg):
self.MYTHREAD = threading.Thread(target=callback, args=arg)
self.MYLOCK = threading.Lock()
self.MYTHREAD.start()
def stop(self):
self.MYLOCK.acquire()
def sleep_for(self, duration, units=MSEC):
self.MYLOCK.acquire()
threading.Timer(duration * units, self.MYLOCK.release).start()


Note that the thread is started when the thread is defined.

As of right now I'm trying to acquire a lock, but I don't think that that is what a lock does. Is this even possible?
