I believe Python 3.8's '=' f-string specifier (
https://docs.python.org/3/whatsnew/3.8.html#f-strings-support-for-self-documenting-expressions-and-debugging)
combined with __name__ does what you'd want:
return f'{self.__class__.__name__}({self.name=}, {self.age=})'
Outside of the __name__ dance, this is a bit more concise (and IMO
readable) than C#'s nameof.
On that note, for simple classes like this, namedtuples or 3.7's
dataclasses would serve the purpose a bit more nicely.
