I am following the official Django documentation and trying to make the polls app. But when I run the command python manage.py shell I get the console error.

The code of my polls/models.py is:

import datetime

from django.db import models

from django.utils import timezone

class Question(models.Model):

    #...

    def was_published_recently(self):

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

    def__str__(self):

        return self.question_text

    question_text = models.CharField(max_length=200)

    pub_date = models.DateTimeField('date published')

class Choice(models.Model):

    #...

    def__str__(self):

        return self.choice_text

    question = models.ForeignKey(Question, on_delete=models.CASCADE)

    choice_text = models.CharField(max_length=200)

    votes = models.IntegerField(default=0)

Please find the error in my code and help me run my code.The error is attached above
