[Python-ideas] Python docs page: In what ways is None special

[David Mertz]

Great work! There are a few typos, I'll try to get to a PR on those.

I wonder if it's worth noting that None is a singleton, while 42 is just a
value. I.e. there might be several distinct objects that happen to be the
int 42, but not so with None.

Of course, in CPython, small integers are cached as the same object, but
larger integers are not necessarily cached. This has varied in details
between Python implementations and even versions, it's not a semantic
promise like None carries.

Maybe that's too far in the weeds for an intro though.
