如何在运行时为嵌套属性构建类映射

import inspect

def build_class_mapping(obj, mapping):
    obj_type = type(obj)
    new_obj = obj_type()

    for attr_name, attr_value in obj.__dict__.items():
        if attr_name in mapping:
            mapped_attr_name = mapping[attr_name]
            setattr(new_obj, mapped_attr_name, attr_value)
        elif inspect.isclass(attr_value):
            mapped_attr_value = build_class_mapping(attr_value, mapping)
            setattr(new_obj, attr_name, mapped_attr_value)

    return new_obj

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

class Address:
    def __init__(self, city, country):
        self.city = city
        self.country = country

person = Person("John", 30, Address("New York", "USA"))

mapping = {
    "name": "fullName",
    "address": "location"
}

mapped_person = build_class_mapping(person, mapping)

print(mapped_person.fullName)  # Output: John
print(mapped_person.location.city)  # Output: New York
print(mapped_person.location.country)  # Output: USA
