I'm tempted to say "you can't", but I'll be more accurate and say "I
don't know how you can do it".
More interesting to me is why you might need to do this? Since
everything is a reference in Python, keeping a variable that contains a
reference to an object (any object!) is no more expensive than keep a
variable that contains a reference to a number representing the objects
id. And, as you say, you're within the same session, so why can't you
keep a reference?
The colder the x-ray table, the more of your body is required on it.
