Writing your first Django app, part 1 -> def __str__(self): problem or misunderstanding of doc?

[TitanFighter]

Hi guys.
I have a problem with the tutorial "Writing your first Django app, part 1" starting from position:

>>> from polls.models import Question, Choice

# Make sure our __str__() addition worked.
>>> Question.objects.all()
[<Question: What's up?>]

# Django provides a rich database lookup API that's entirely driven by
# keyword arguments.
>>> Question.objects.filter(id=1)
[<Question: What's up?>]
>>> Question.objects.filter(question_text__startswith='What')
[<Question: What's up?>]

In all cases I receive:
[<Question: Question object>] instead of [<Question: What's up?>]

I have Ubuntu 15.04_64 and run Python 3.4.3 via "python3 manage.py shell", because Ubuntu has built-in Python 2.*

My code is like:

import datetime

from django.db import models
from django.utils import timezone

class Question(models.Model):
	question_text = models.CharField(max_length=200)
	pub_date = models.DateTimeField('date published')

	def __str__(self):              # __unicode__ on Python 2
		return self.question_text

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

class Choice(models.Model):
	question = models.ForeignKey(Question)
	choice_text = models.CharField(max_length=200)
	votes = models.IntegerField(default=0)

	def __str__(self):              # __unicode__ on Python 2
		return self.choice_text

If something wrong with the code, maybe is it possible to edit this section in tutorial to make it a bit clearer? Or is this problem somewhere else?
Thanks.

Did you "start a new Python interactive shell by running python manage.py shell"? If you use the old one, the new methods won't take effect.

Yes, i did. Didn't resolve the problem.

Hm, I don't see an obvious problem then. Please see TicketClosingReasons/UseSupportChannels for more ways to get help and reopen this ticket if there's something we should add to the docs after you get it working. Thanks!
