On Python 3.5.2 mock.Mock() is equal to mock.ANY, but mock.MagicMock() is not.

Minimal example:

In Python 3.5.2:
>>> from unittest import mock
>>> mock.Mock() == mock.ANY
True
>>> mock.ANY == mock.Mock()
True
>>> mock.MagicMock() == mock.ANY
False
>>> mock.ANY == mock.MagicMock()
True

From a checkout in last week.

Python 3.7.0a0 (default:c163a76163f7, Jan 15 2017, 22:20:24) 
[GCC 6.3.1 20161221 (Red Hat 6.3.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from unittest import mock
>>> mock.ANY == mock.Mock() 
True
>>> mock.ANY == mock.MagicMock() 
True

Kushal I think the OP is reporting `mock.MagicMock() == mock.ANY` is False while `mock.ANY == mock.MagicMock()` is True which is still the case in 3.7. A related issue is #25195. In that issue Serhiy has mentioned this behaviour(http://bugs.python.org/issue25195#msg259822).

Now I understood, thanks. I think I should have more coffee before commenting on bugs :)

Proposed patch fixes comparing MagicMock with ANY.

Serhiy's patch looks pretty good to me, thanks! Also, thanks for the report, Rafael. I definitely forgot to fix this case after fixing issue 25195.

Thanks Berker.

Maybe _Call.__eq__ also should return NotImplemented in some cases, but I don't have a demonstrating example.
