我正在编写一个脚本，它发送 facebook 消息，告诉日出和日落时间。时间在上午 10 点发送到接收者列表。我计算时间的方法是：当脚本运行时，我得到时间，然后我从网页上抓取日出/日落时间，计算到最快的时间（比如说日出），然后睡觉发送消息，然后睡到日落并发送另一条消息，等等。该脚本适用于第一条消息，但不适用于第二条消息。发送第一条消息后，它会显示在第二条消息之前它将休眠多长时间，并且它始终是正确的时间量，但是，它似乎并没有从该睡眠中醒来。关于这里发生的事情的任何想法/是否有更好的方法来完成任务？

print('{}:{} left!'.format(wait_time //3600, wait_time //60%60))
time.sleep(rem - 20) # 20 seconds earlier because sending the messages takes about 20 seconds
