AttributeError: 'function' object has no attribute 'urlparse'

Checklist

• I have verified that that issue exists against the master branch of Django REST framework.
• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• This is not a usage question. (Those should be directed to the discussion group instead.)
• This cannot be dealt with as a third party library. (We prefer new functionality to be in the form of third party libraries where possible.)
• I have reduced the issue to the simplest possible case.
• I have included a failing test as a pull request. (If you are unable to do so we can still accept the issue.)

Steps to reproduce

In any Django 1.11 project with a python2.7 interpreter, latest DRF version:

# In a Django Shell
from rest_framework.compat import urlparse,
urlparse.urlparse('https://google.fr')

Expected behavior

A ParseResult object should be returned, from what I see here :
https://github.com/encode/django-rest-framework/blob/master/rest_framework/renderers.py#L997

Actual behavior

Results in : AttributeError: 'function' object has no attribute 'urlparse'
Same example works under Python3

More details:

It looks like this issue has been introduce by this commit : 8908934#diff-ce493f71b3679e91b72126c168670399R25 . A possible fix could be to replace ligne 25 of compat.py (actually from urlparse import urlparse # noqa) by import urlparse # noqa (or a weirder import urlparse as urlparse # noqa)

I noticed that by trying to access the http://localhost:8000/ws/schema.json URL on my localhost. See paste for more details : https://pastebin.com/raw/51QgEcqG

If this is indeed an issue, I am volunteer to try and write a few tests so that type of cases get detected by the tests matrix.

I was not (yet ?) able to create a proper test inside of DRF test suite to test this issue but the following snippet does reproduce the issue:

from rest_framework.renderers import (CoreJSONRenderer, JSONOpenAPIRenderer, OpenAPIRenderer)
from rest_framework.schemas.generators import SchemaGenerator

options = {"url": "Foo", "title":"Bar", "description": "Desc"}

generator = SchemaGenerator(url=options['url'], title=options['title'],description=options['description'] )

schema = generator.get_schema(request=None, public=True)

renderer = OpenAPIRenderer()

output = renderer.render(schema, renderer_context={})

Closing, as Python 2 support has been dropped. Thanks for trying to reproduce this.
