It started with writing type hints for a complex dict, which led me to TypedDict, slowly went into “why can’t I just do a dataclass as with the rest”.

Found two libraries:

• pydantic
  • Really nice esp. for validation
  • MyClass(**somedict)
  • Couldn’t find an easy way to parse nested dataclasses from the same dict
• Dataclass Wizard
  • Basically a wrapper to read/save (nested!) dataclasses from dicts / json.
  • Does one thing and does it well!
  • When dumping, converted my field_names to camelcase fieldNames, one can disable that from settings: Extending from Meta — Dataclass Wizard 0.22.1 documentation
