No Module Named Module Name

 I have Created the Project and App using Python And Django.
 This is My Model in my model.py
 --------------------------------------------------------------------------------------
 class Poll(models.Model):
     question = models.CharField(max_length=200)
     pub_date = models.DateTimeField('date published')
 --------------------------------------------------------------------------------------
 Now When run "import Poll or from polls.models import Model" through python shell , it gives no module named

 Poll Error.
