在 Python 中为日期添加时间

Question

我想为日期添加时间。日期和时间是字符串

12/28/2018 23:30:00

现在在这里我想添加时间

02:30:00

在输出中：

12/29/2018 02:30

我尝试了以下方法：

import datetime
from datetime import datetime, timedelta

departure_time = "15:30"
duration = "00:00:50"

#I convert the strings to datetime obj
departure_time_obj = datetime.strptime(departure_time_obj, '%H:%M')
duration_obj = datetime.strptime(duration_obj, '%H:%M:%S')

arrival_time = dtt + datetime.timedelta(duration_obj)
print(arrival_time)

我收到以下错误：

AttributeError: type object 'datetime.datetime' has no attribute 'timedelta'

Answer 1

用 timedelta(hours=duration_obj.hour, minutes=duration_obj.minute, seconds=duration_obj.second)

前任：

from datetime import datetime, timedelta

departure_time = "15:30"
duration = "00:00:50"

#I convert the strings to datetime obj
departure_time_obj = datetime.strptime(departure_time, '%H:%M')
duration_obj = datetime.strptime(duration, '%H:%M:%S')

arrival_time = departure_time_obj + timedelta(hours=duration_obj.hour, minutes=duration_obj.minute, seconds=duration_obj.second)
print(arrival_time)

注意：您已经导入timedelta
