Why is the id of a Python class not unique when called quickly?

Question

I\'m doing some things in Python (3.3.3), and I came across something that is confusing me since to my understanding classes get a new id each time they are called.

Answer 1

Try this, try calling the following:

a = someClass()
for i in range(0,44):
    print(someClass())
print(a)

You'll see something different. Why? Cause the memory that was released by the first object in the "foo" loop was reused. On the other hand a is not reused since it's retained.
