Are the following two expressions the same?
x is y
Id(x) == id(y)

Listen to MRAB, ignore me.
That is all.
Well, apart of Joshua's qualifications, that is! :-)
Let's make it clear for the OP, since this thread seems to have wandered into
the realms of the confusing, for what is a basic question.
The short answer is "yes".
The longer answer is:
if nobody else is fiddling with "x" and "y"
and if id() is the normal builtin python "id" function
Then yes.
The "is" test is more direct and less subject to iffiness because the longer
expression using id() leaves more scope/time for things to change, and of
course "id" itself can be rebound to something weird.
