python - How to get class variables and type hints?

Question

Assume I define a class with class level variables with type hints (e.g. something like the new python 3.7 dataclasses)

class Person:
    name: str
    age: int

    def parse_me(self):
        "what do I do here??"        

How can I get the pairs of (variable name, variable type)?

Answer 1

typing.get_type_hints is another method that doesn't involve accessing magic properties directly:

from typing import get_type_hints

class Person:
    name: str
    age: int

get_type_hints(Person)
# returns {'name': <class 'str'>, 'age': <class 'int'>}
