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.

I have worked with both C# and Python for a while now and there is one feature of C# I'm missing in the Python language.

This feature is the "nameof" operator. (https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/nameof).
The place I use this the most in C# is in `ToString()` methods or logging messages.
This makes sure the developer cannot forget to update the name of a member.

As an example I created this `Person` class.

```
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __repr__(self):
        return f"Person(name: {self.name}, age: {self.age})"
```

With the `nameof` operator this would look like the following:

```
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __repr__(self):
        return f"{nameof(Person)}({nameof(self.name)}: {self.name}, {nameof(self.age)}: {self.age})"
```

What do you think about this?
