Python - Using ViewSet, Generics and Mixin together in Django REST Framework?

I just started learning about DRF. We know that with generics and mixin Django REST Framework makes handling GET, POST, PUT, DELETE etc easy for users. And another feature is ViewSets. It helps us to achieve Don't Repeat Your code principle.

So, I have my old views.py file like this before:

class SnippetList(generics.ListCreateAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

class SnippetDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

I updated my views.py like this:

class SnippetViewSet(viewsets.GenericViewSet, generics.ListCreateAPIView,
                     generics.RetrieveDestroyAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

i removed SnippetList and SnippetDetails (I don't know if its correct to do. But, in both of the classes we are repeating same code. So I thought with new SnippetViewSet I should delete both.)

Here is my urls.py :

from django.urls import path, include
from rest_framework.urlpatterns import format_suffix_patterns
from .views import SnippetViewSet, UserList, UserDetail
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register('snippets', SnippetViewSet)

urlpatterns = [
    path('', include(router.urls))
]

urlpatterns = format_suffix_patterns(urlpatterns)

I am getting this error when I am running my application.

ImportError: cannot import name 'SnippetList' from 'snippets.views' (D:\Python Training\DRF\Tutorial\tutorial\snippets\views.py). Did you mean: 'SnippetViewSet'?

I tried to use ViewSets and Generics together but cannot manage to do it. I am expecting to:

1. See all my data when i go on /snippets and also able to post new snippet
2. See detailed view when i browse /snippets/id and also options for putting and deleting.
