Repeat a task in Python

Question

I'm working on a simple shell program with Python, and I need to repeat a task (a simple os.system call ) every second.

Is it possible to make that, without interrupting the program flow ? Like a multithreaded thing?

Thanks in advance.

without threading

import time

while True:
   time.sleep(1)
   do_stuff()

with threading

import threading 
import time

def my_func():
  while True:
    time.sleep(1)
    do_stuff()

t1 = threading.Thread(target=my_func)  

t1.start()
