"None" doesn't display as I expected in Python interactive mode

Question

I thought that displaying in Python interactive mode is always equivalent print(repr()), but this is not the case for None. Is this a linguistic function or am I missing something? Thanks you

>>> None
>>> print(repr(None))
None
>>>
