Type mapping
Strings become str, integers int, decimals float, booleans bool, arrays List[T] and nested objects their own TypedDict class.
Frequently asked questions
Why TypedDict instead of dataclasses?
TypedDict describes plain dictionaries produced by json.loads without requiring conversion, which matches typical JSON handling.
How are null values typed?
