①兩個時間差

②減去1天2個小時3分鐘4秒（加負數(shù)）

# -*- encoding=utf-8 -*-import datetimetime_str = ’2021-01-28 10:00:00’time_date = datetime.datetime.strptime(time_str, ’%Y-%m-%d %H:%M:%S’)print(’原始時間:tttt{}’.format(time_date))add_info = datetime.timedelta(days=-1, hours=-2, minutes=-3, seconds=-4)add_end = time_date + add_infoprint(’減去1天2個小時3分鐘4秒后:t{}’.format(add_end))
