from datetime import datetime
from apscheduler.scheduler import Scheduler
import time 

def tick():
    print('Tick! The time is: %s' % datetime.now())


if __name__ == '__main__':
    scheduler = Scheduler()
    scheduler.add_interval_job(tick, seconds=1)

    print('Press Ctrl+C to exit')

    scheduler.start()

    time.sleep(10)

每秒钟执行一次tick函数， 在主进程中开线程
