How to loop through functions every 30 minutes, hour, etc?

Question

Python

There are many different functions that parse data, each of them should be triggered every 30 minutes, an hour, and so on. How can it be implemented?

Answer 1

Times option:

import sched, time

s = sched.scheduler(time.time, time.sleep)

def f():
    s.enter(5, 1, f)  # Перезапуск через 5 секунд
    print(time.time())

f()
s.run()

Two option:

import threading

def f():
  threading.Timer(5.0, f).start()  # Перезапуск через 5 секунд
  print("Hello!")

f()

A very stupid one:

import time

def f():
  print("Hello!")

while True:
    time.sleep(5)
    f()

Answer 2

Linux has a job scheduler called cron.

Answer 3

better sistemd.timer - more options and options.
