How to stop the execution of the loop after a certain time without interfering with the code that is being executed in the loop?

Question

Python

The loop performs a certain function, and after a while it must finish executing the function, and the loop itself.
Here is the loop itself:

for i in range(100):
  new_people_and_actions()

Answer 1

Maybe, if we are talking about time, then do this:

import time
stop = time.time() + 10 # сколько секунд будет выполняться функция

while stop > time.time():
    new_people_and_actions()

Answer 2

add an external marker, such as a file, a flag, send a signal.
Add its handling inside the loop to complete correctly.
