Sarcasm and a lack thereof is very hard to see over the Internet. It's
probably just a misunderstanding :).

Actually, it is giving you the id of the int(10) object. Maybe it's an
address, maybe it's not. Only your implementation knows for sure.

Aha. Thanks, Ned. This is the answer I was looking for.
I use logging in the real classes, and thought that turning setting
the level to logging.DEBUG once was easier than hunting down four

Thanks Tim,
This takes me to one more question.
'is' operator is used to compare objects and it should not be used to
compare data.
So can it be compared with 'False'.
i.e. Is this code possible
if a is False:
print 'Yes'
if b is False:
print 'No'
Because i recommended this should not

You would use that if you want to check if a/b is the exact bool value
False. Normally you would simply spell it thus:
