python 获取今天凌晨的时间

python 获取今天凌晨的时间

now = datetime.datetime.now()
zero_today = now - datetime.timedelta(hours=now.hour, minutes=now.minute, seconds=now.second,
                                                  microseconds=now.microsecond)

获取当前时间的前X 天，则可以用一下写法：

deadline_time = str(zero_today + datetime.timedelta(days=-13))
