Python 获取当天零点时间戳

import time
import datetime


def zero_timestamp():
    """获取本地时间当天零点时间戳

    Returns: int

    """
    return int(time.mktime(
        datetime.date.today().timetuple()
    ))

assert zero_timestamp() == 1645027200 # True 2022/02/17

通过 datetime.date.today() 获取当天的日期 输出格式 %Y-%m-%d

timetuple() 返回时间结构元组 当天的时分秒都为零了

time.struct_time(tm_year=2022, tm_mon=2, tm_mday=17, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=48, tm_isdst=-1)

time.maketime() 将时间元组转换为时间戳

def mktime(t: _TimeTuple | struct_time) -> float: ...
