difference between get and filter in django

Difference between Django's filter() and get() methods

Basically use get() when you want to get a single unique object, 
and filter() when you want to get all objects that match your lookup parameters
which means filter() is slightly expensive operation if the model class has a large number of objects, whereas get() is direct approach.

...     headline__startswith='What'
... ).exclude(
...     pub_date__gte=datetime.date.today()
... ).filter(
...     pub_date__gte=datetime.date(2005, 1, 30)
... )
