问题描述
我本以为这个问题已经有了答案，但似乎没有.在 Python 中，我想计算从现在"到今天"或明天"指定时间的秒数，无论何时发生(例如，下一次发生在 6:30 AM).计划是倒计时秒数并在指定时间触发音乐警报.我对 Python 还很陌生，到目前为止，datetime 文档并没有帮助我解决这个问题.有人可以给我一些帮助吗?
I would have thought this question would already have an answer, but it doesn't seem to. In Python, I want to calculate the number of seconds from "now" to a specified time "today" or "tomorrow," whenever it next occurs (e.g., the next occurrence of 6:30 AM). The plan is to count down seconds and set off a musical alarm at the specified time. I'm pretty new at Python, and the datetime documentation hasn't helped me with this so far. Can somebody give me some assistance with this?
推荐答案
这应该可以:
from datetime import datetime, timedelta
now = datetime.now()
(timedelta(hours=24) - (now - now.replace(hour=6, minute=30, second=0, microsecond=0))).total_seconds() % (24 * 3600)
