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

[Chris Barker - NOAA Federal]

> None is keyword, and just like any other keyword, it can't be re-bound.


>> it's only a keyword because Python doesn't otherwise have a way of creating non-rebindable names.  It's purpose is to represent the singular object of NoneType, and in that sense it's a literal as much as [] or "".

We’re getting kind of pedantic here, but no, it’s not “as much as” —
[] and “” create new instances of a list or string.

For the purposes of this document, however, these are pretty esoteric
distinctions.

What the docs should make clear is that None ( and True and False ) is
a singleton— None will always refer to the SAME None object.

And that can be demonstrated by showing that you can’t rebind the name None.

But I think it’s misleading to say that that is the same as:

42 = “something else”

None is syntactical a name like any other — what’s special about is
that it can’t be rebound.
