strict

Pydantic strict mode rejects input that is not already the expected type instead of coercing it. Enable it for a validation call, a field, or a model configuration.

Syntax

model_validate(data, strict=True)
TypeAdapter(type).validate_python(data, strict=True)
Field(strict=True)
ConfigDict(strict=True)
