FAQ for Dataclass To Dict

  • How do I convert a data class to a dict?

    You can use dataclasses.asdict (note that this is a module-level function and is not bound to a Dataclass instance) and is designed just for that purpose. Converts the data class instance to a dict (using the dict_factory factory function).

  • When should a data class be used instead of a dictionary?

    A DataClass is not intended to necessarily replace a dictionary. Rather, it is used as an object to store some data where it makes sense when modeling an application. Let's say we create a simple address book. Assuming only some data is stored, the Person class can be a data class with fields like name, phone_number, and so on.

  • What is a @dataclass?

    This class is intended to be a simplified representation of an HTTP response. To create a data class, all we have to do is use the @dataclass decorator on a custom class like this: The previous example creates a response class with status and body attributes. The @dataclass decorator gives us these benefits by default:
