How to repeat a function every N minutes?

Question

In my python script I want to repeat a function every N minutes, and, of course, the main thread has to keep working as well. In the main thread I have this:

# something
# ......
while True:
  # something else
  sleep(1)

So how can I create a function (I guess, in another thread) which executes every N minutes? Should I use a timer, or Even, or just a Thread? I'm a bit confused.

Solution

use a thread

import threading

def hello_world():
    threading.Timer(60.0, hello_world).start() # called every minute
    print("Hello, World!")

hello_world()

It's a decent answer, but it introduces a drift (always minimally longer than the interval), this answer is more accurate over time:
