Not that this causes your problem, but I'd still like to point out that
'id' is the name of a built-in function. Shadowing built-in names can
lead to surprising behavior.

Yes. "==" tests whether two objects are equal, whereas "is" tests
whether two objects are actually the same object. Examples:

Two different list objects with equal contents:

>>> a = [1,2,3]
>>> b = [1,2,3]
>>> a==b
True
>>> a is b
False

Two names for the same list object:

>>> a = [1,2,3]
>>> b = a
>>> a==b
True
>>> a is b
True

Hope this helps,
