Variables are not objects and so they have no attributes.
You can't really de-reference the object being referenced as it can
potentially contain multiple references, but an innacurate way of doing
this would be, e.g.
>>> x = [1, 2, 3]
>>> y = x
>>> g = globals()
>>> varnames = [i for i in g if g[i] is x]
But this cries the question: why do you want to do this? And usually
that question is asked when someone thinks that a: you shouldn't need to
do this and b: whatever the desired effect there is probably a better
way of accomplishing it.
