from dataclasses import dataclass
import dataclass_factory
@dataclass
class Book:
title: str
price: int
author: str = "Unknown author"
data = {

Requirements
- python >= 3.6
You can use dataclass_factory with python 3.6 and dataclass library installed from pip.
On python 3.7 it has no external dependencies outside of the Python standard library.
Advantages
- No schemas or configuration needed for simple cases. Just create
Factoryand callload/dumpmethods - Speed. It is up to 10 times faster than
marshmallowanddataclasses.asdict(see benchmarks) - Automatic name style conversion (e.g.
snake_casetoCamelCase) - Automatic skipping of "internal use" fields (with leading underscore)
- Enums, typed dicts, tuples and lists are supported out of the box
- Unions and Optionals are supported without need to define them in schema
- Generic dataclasses can be automatically parsed as well
- Cyclic-referenced structures (such as linked-lists or trees) also can be converted
- Validators, custom parser steps are supported.
- Multiple schemas for single type can be provided to support different ways of parsing of the same type
