Adding time to a date in Python

Question

I would like to add time to a date. Date and time are strings

12/28/2018 23:30:00

now in this i would like to add Time

02:30:00

in output:

12/29/2018 02:30

I've tried the following:

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)

I get the following error:

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

Your import is wrong. Since you're importing Timedelta directly using "from ... import ..." You don't need to write datetime.timedelta but instead just timedelta — Ian Rehwinkel

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

Ex:

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)

Note: You have already imported timedelta
