Why is Python datetime time delta not found?

Question

I am trying to make an array of dates in mmddyyyy format. The dates will start on the current day and then go two weeks into the future. So it all depends on the starting date. When I run my code I get an error that states:

Traceback (most recent call last):
File "timeTest.py", line 8, in <module>
day = datetime.timedelta(days=i)
AttributeError: type object 'datetime.datetime' has no attribute 'timedelta'

I am not sure why this is happening because after searching online, I noticed that people are using the ‘timedelta’ in this way.

Here is my code:

import time
from datetime import datetime, date, time, timedelta

dayDates = []
today = datetime.now()
dayDates.append(today.strftime("%m%d%Y"))
for i in range(0,14):
    day = today + datetime.timedelta(days=i)
    print day

Answer 1

You already imported timedelta. You don’t need to access it through datetime.

import time
from datetime import datetime, date, time, timedelta

dayDates = []
today = datetime.now()
dayDates.append(today.strftime("%m%d%Y"))
for i in range(0,14):
    day = today + timedelta(days=i)
    print day

The method you want to call is datetime.timedelta, as seen here. datetime is the module containing timedelta.

If you look at your import line:

from datetime import datetime, date, time, timedelta

…you’ll see you’re importing the datetime class from the datetime module. So, when you call datetime.timedelta, you’re actually calling datetime.datetime.timedelta, which doesn’t exist.

Answer 3

import time
from datetime import datetime, date, time, timedelta

dayDates = []
today = datetime.now()
dayDates.append(today.strftime("%m%d%Y"))
for i in range(0,14):
    day = today + datetime.timedelta(days=i)
    print day

The error that you are getting says, that datetime has no attribute timedelta. It happens, because you have imported from datetime specific things. In order to access timedelta now you type timedelta instead of datetime.timedelta.

import time
from datetime import datetime, date, time, timedelta

dayDates = []
today = datetime.now()
dayDates.append(today.strftime("%m%d%Y"))
for i in range(0,14):
    day = today + timedelta(days=i)
    print day

Like that, your code should work properly. Also, pay closer attention to the error messages and try to read them carefully. If you focus enough, you often can sort out the problem basing on them on your own.
