11. Mixins Mixin classes help add any additional functionalities to some classes using multiple inheritances. Implement two classes DictMixin and JSONMixin, that add a function to_dict and to json respectively. They should convert a Python class to a dictionary and JSON. They should only convert object attributes that do not start with '_' (underscore). If some class is not convertible to JSON, raise a TypeError with the message "Object is not JSON serializable" (without quotes). For Example, name="abc", data = 10, secret = "secret", class MyClass(DictMixin, JSONMixin): definit__(self, name, data, secret): self.name = name self.data = data self._secret = secret obj MyClass("abc", 10, "secret") In the above code obj.to_dict() should return {'name': 'abc', 'data': 10), and obj.to_json() should return {"name": "abc", "data": 10).
