复杂地将嵌套字典转换为python中的对象

class NestedDictToObject:
    def __init__(self, nested_dict):
        self.__dict__.update(nested_dict)
        for key, value in self.__dict__.items():
            if isinstance(value, dict):
                self.__dict__[key] = NestedDictToObject(value)

nested_dict = {
    'name': 'John',
    'age': 25,
    'address': {
        'street': '123 Main St',
        'city': 'New York',
        'country': 'USA'
    }
}

obj = NestedDictToObject(nested_dict)
print(obj.name)  # Output: John
print(obj.age)  # Output: 25
print(obj.address.street)  # Output: 123 Main St
print(obj.address.city)  # Output: New York
print(obj.address.country)  # Output: USA
