Problems with code in shell (Django 2 and python 3.6)

[User1]

Hello, I am practicing the tutorial part 5, Test and I got an error I can solve.

The code in shell is:

(mientorno) C:\Users\user1\djangowom>python manage.py shell

Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)]

 on win32

Type "help", "copyright", "credits" or "license" for more information.

(InteractiveConsole)

>>>

>>>

>>>

>>> import datetime

>>> from django.utils import timezone

>>> from polls.models import Question

>>> future_question = Question(pub_date=timezone.now() + datetime.timedelta(days=30))

>>> future_question.was_published_recently()

Traceback (most recent call last):

  File "<console>", line 1, in <module>

  File "C:\Users\arojas\djangowom\polls\models.py", line 12, in was_published_re

cently

    return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

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

Any idea? Thanks a lot.

You're missing an additional datetime. Either:

>>> from datetime import datetime

or

>>> future_question = Question(pub_date=timezone.now() + datetime.datetime.timedelta(days=30))

When I started with Python, that confused the heck out of me: The datetime *module* has a datetime *class* in it. The datetime class really should be called DateTime, but it's been around too long to change it now, I guess.

HTH,

Stefan

It's possible that exist and confusion using libraries due to the versions of python. Try this in the import :

from datetime import datetime
