I'm not sure how this compares to what nameof(Person) should return,
but the above idiom (or something like it) is very common in Python,
as it allows repr to acknowledge a subclass. If you create "class
Martian(Person): pass", then a Martian's repr will say "Martian". On
the other hand, if you actually want "the name of the surrounding
class", then that can be spelled __class__.__name__, and that will
always be Person even if it's been subclassed. Not nearly as common,
but available if you need it.
I'm not sure what you mean, but:
--> class Person:
... def __init__(self, name):
... self.name = name
... def __repr__(self):
... return '%s(name=%r)' % (self.__class__.__name__, self.name)
...
--> class Martian(Person):
... pass
...
--> p = Person('Ethan')
--> m = Martian('Allen')
--> p
Person(name='Ethan')
--> m
Martian(name='Allen')
(Same results with f-strings. Whew!)

~Ethan~
