cron_lite

A very light library to run python functions like cron jobs do. (support cron expressions with timezone, decorator style, spawn running and graceful exit. Runs in python service like Apscheduler, no effect of system config)

Example

from cron_lite import cron_task, start_all, stop_all, set_time_zone
import time

set_time_zone("Asia/Shanghai")


@cron_task("* * * * * 0/2")
def event1():
    print("event1", time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time())))
    time.sleep(3)
    print("event1 done", time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time())))

@cron_task("* * * * * 0/15")
def event2():
    print("event2", time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time())))
    time.sleep(10)
    print("event2 done", time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time())))


th = start_all(spawn=True)  # use bare `start_all()` to run forever as a service
print("start")
time.sleep(60)
print("stop")
stop_all(th)
print("done")
