In Python, is object() equal to anything besides itself?

Question

If I have the code my_object = object() in Python, will my_object be equal to anything except for itself?

I suspect the answer lies in the

Answer 1

object doesn't implement __eq__, so falls back on the default comparison id(x) == id(y), i.e. are they the same object instance (x is y)?

As a new instance is created every time you call object(), my_object will never* compare equal to anything except itself.

This applies to both 2.x and 3.x:

# 3.4.0
>>> object().__eq__(object())
NotImplemented

# 2.7.6
>>> object().__eq__(object())

Traceback (most recent call last):
  File "", line 1, in 
    object().__eq__(object())
AttributeError: 'object' object has no attribute '__eq__'

* or rather, as roippi's answer points out, hardly ever, assuming sensible __eq__ implementations elsewhere.
