我在DB中有2个参数：启动和停止。它们的值可以是例如07：00-23：00或23：00-07：00（07之后开始，23之后停止或23之后开始，07之后停止）
在那个时候，状态必须是0或1，假设它是LED
如何创建不会在午夜前后混乱的统一逻辑控制器？
我的执行不力（无法正常工作）如下。实际上，我已经尝试了许多变体，但仍然以目前的状态结束。

更新后的版本。确定相对于终点的当前位置。如果午夜过去，则将结束日期设置为明天

有两种情况：当前时间在给定时间（顺时针）或外部（想象时钟圈）之间：
#!/usr/bin/env python from datetime import datetime def in_between(now, start, end): if start < end: # e.g., "07:00-23:00" return start <= now < end elif end < start: # e.g., "23:00-07:00" return start <= now or now < end else: # start == end return True # consider it 24 hour interval now = datetime.now().time() for date_range in ["07:00-23:00", "23:00-07:00"]: start, end = [datetime.strptime(s, "%H:%M").time() for s in date_range.split("-")] not_ = '' if in_between(now, start, end) else 'not ' print("{now:%H:%M} is {not_}in between {date_range}".format(**vars()))
02:26 is not in between 07:00-23:00 02:26 is in between 23:00-07:00
