Is there anything in Python that is a `NoneType` besides `None`?

Question

I was just wondering if in Python there's any other object/instance whose type is NoneType type besides the very well known None:

>>> type(None)
<type 'NoneType'>

So... This is very clear, but I was wondering whether there's anything else that is also of NoneType

>>> type(???)
<type 'NoneType'>

Needless to say, this is just for curiosity sake and learning purposes :-)

Thank you in advance.

Welp, if an answer answers a question in an indirect dupe, it's still a dupe. — cs95, Aug 22 '17 at 22:09
You're right... it's a duplicate (I saw that question, and I didn't get as far as to reach the 3rd entry) I'll accept the first answer and remove it — Savir, Aug 22 '17 at 22:10
@BorrajaX Relax. There's nothing wrong with dupes. They serve as checkpoints to guide people who enter different search terms but are looking for the same thing. — cs95, Aug 22 '17 at 22:10

Ok... That makes sense @cᴏʟᴅsᴘᴇᴇᴅ ... I'll keep it for now. Thank you. — Savir, Aug 22 '17 at 22:23

From the docs, None is:

The sole value of the type NoneType.

People that read the documentation to find answers? – a p Aug 22 '17 at 22:07
I did, `a p`, but it's no so clear in the Python 2 docs, which is what I use (https://docs.python.org/2/library/types.html#types.NoneType) – Savir Aug 22 '17 at 22:08

It's in python 2 docs too: https://docs.python.org/2/library/constants.html – roganjosh Aug 22 '17 at 22:10

None is the only NoneType , however in your case of

>>> type(???)
<type 'NoneType'>

You could do something like

>>> a=None
>>> type(a)
type 'NoneType'

Meaning, any variable that holds None will obviously also return NoneType as its type since they are None.

`a` is not a value; it's just another name that refers to the singleton value of type `NoneType`. – chepner Aug 22 '17 at 22:12
That's why I included the example with `a` , since the asker's question wonders `whether there's anything else`, so I took that to include names that refers to the very same `NoneType`. – Davy M Aug 22 '17 at 22:15
