How to use sched?

Question

Python

There is such a simple piece of code.

import sched, time  
s = sched.scheduler(time.time, time.sleep)
def print_time(a='default'):
    print("From print_time", time.time(), a)
    
def print_some_times():
    tim = time.time()
    # print(tim)
    s.enter(10, 1, print_time)
    s.enter(5, 2, print_time, argument=('positional',))
    s.enter(5, 1, print_time, kwargs={'a': 'keyword'})
    s.run()
    print(time.time() - tim)

tim1 = time.time()
for i in range(5):
    print_some_times()
    print(time.time() - tim1)

Where do I need to insert time.sleep(0.1) so that the period does not change?
