Why does id({}) == id({}) and id([]) == id([]) in CPython?

Question

Why does CPython (no clue about other Python implementations) have the following behavior?

tuple1 = ()
tuple2 = ()                                                    


        

Answer 1

The == operator on lists and dicts do not compare the object IDs to see if they the same object - use obj1 is obj2 for that.

Instead the == operator compares the members of the list of dict to see if they are the same.
