When I create 2 different dicts with the same literal, their dict.values() are equal in python2 but not equal in python3.
Here is an example in python2:
 $ python2
 Python 2.7.16 (default, Mar 4 2019, 09:02:22)
 [GCC 4.2.1 Compatible Apple LLVM 10.0.0 (clang-10001145.5)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> a = {'hello': 'world'}
 >>> b = {'hello': 'world'}
 >>> a.values() == b.values()
 True
 >>> a.keys() == b.keys()
 True
However, the dict.values() are not equal in python3:
 $ python3
 Python 3.7.2 (default, Feb 12 2019, 08:16:38)
 [Clang 10.0.0 (clang-10001145.5)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> a = {'hello': 'world'}
 >>> b = {'hello': 'world'}
 >>> a.values() == b.values()
 False
 >>> a.keys() == b.keys()
 True
Is this a bug? Or is this behavior specified somewhere in the documentation? Thanks.
