How to import views from one django views.py to another

I am learning Django. I have 2 functions in my app, one for cats, and another for dogs (as an example). I have the following folder structure:

/myproject/templates <-- dogs.html, cats.html
/myproject/dogs/ <-- views.py, models.py etc
/myproject/cats/ <-- views.py, models.py etc

Now both cats and dogs have shared views, etc, but currently I am just repeating these in each views.py file. Is there a way to "import" views and definitions from one view to another quickly?

This would save me cut and pasting a lot of the work.

What are the dangers of this? E.g. could conflicts arise? etc.

The simplest thing is to have the URLs for cats and dogs point to the same views:

urlpatterns = patterns(
    'catsanddogs.views',
    url(r'^(?P<kind>dog|cat)/(?P<id>\d+)$', 'details'),
)

And then in catsanddogs.views:

def details(request, kind, id):
    if kind == "dog":
        ... whatever is specific to dogs ...
    elif kind == "cat":
        ... whatever is specific to cats ...
    else:
        raise ValueError("...")

    ... whatever applies to both ...
    return HttpResponse(...)

sure, you can use inheritance and you should use CBV in this case

import Animal

class Dog(Animal):
    ....
    pass

class Cat(Animal):
    ....
    pass

You must change your urls.py as well

from django.conf.urls import url
from dogs.views import Dog
from cats.views import Cat

urlpatterns = [
    url(r'^dog/', Dog.as_view()),
    url(r'^dog/', Cat.as_view()),
]
