A Python dataclass simplifies the setup of a class with many attributes. By adding the `datacass` decorator to a `Class` you can any number of typed attributes and it will generate an `__init__` method for you with default values. This is convenient when you are modeling a data heavy application and using classes (rather than dicts) to get better type check errors.
