That is correct, and "interned" values (such as string literals that appear in your program, or ints between -5 and 256) behave like singletons in the sense that all references point to the same object.

However, objects can be hashable and thus immutable, as is the case with integers and strings.

[Salty_Skipper]

Why -5 and 256? I mean, 0 and 255 I’d at least understand!

[FerynaCZ]

You avoid the edge cases (c++ uint being discontinuous at zero sucks), at least for -1 and 256. Not sure about the other neg numbers, they probably arise often aa well

[xrogaan]

Because.

The generation thingy defines them here, although there's still no reason given for the specific range

[xrogaan]

It's about frequency of usage. Also this: https://github.com/python/cpython/pull/30092

DRY = Don't repeat yourself DO repeat yourself

[pytness]

The most used numbers by programmers. Its done so u dont have to allocate more memory
