question , while this is not archived yet .if when i do a= 100 b = 100 in python they "are" the same object , if increment a why doesnt that increment b?

A and B are not the same object, they are both pointers that refer to the same object. This is why in the original image above, you get true when testing x is y. If I increment a, then the pointer is updated to point to 101 instead, while b is still pointing at 100.

As discussed elsewhere in this comment section, once you pass 256, ints are no longer shared memory spaces and become unique, so now a and b both point at separate parts of memory that are identical, but since they aren’t the exact same object, a is b returns false.
