Maybe this will help:
Python 3.5.3+ (default, Jun 7 2017, 23:23:48)
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> False == 0
True
>>> False is 0
False
=====> Just wondering: Is this 'is' test depending on an implementation detail of cPython (small ints, I forgot how small 0-255 maybe, are singletons)?
