<p>可以选择使用Python模块apscheduler。</p>
<pre><code>from datetime import datetime
import time
import os
from apscheduler.schedulers.background import BackgroundScheduler
def tick():
print('Tick! The time is: %s' % datetime.now())
if __name__ == '__main__':
scheduler = BackgroundScheduler()
scheduler.add_job(tick, 'interval', seconds=3)
scheduler.start()
print('Press Ctrl+{0} to exit'.format('Break' if os.name == 'nt' else 'C'))
try:
# This is here to simulate application activity (which keeps the main thread alive).
while True:
time.sleep(2)
except (KeyboardInterrupt, SystemExit):
# Not strictly necessary if daemonic mode is enabled but should be done if possible
scheduler.shutdown()
</code></pre>
