pydantic

What problem does it solve?

Pydantic provides a robust framework for validating and parsing complex Python data into typed models at runtime, reducing boilerplate and preventing invalid data from propagating through applications.

Core Features & Use Cases

• Runtime validation and coercion of Python data into BaseModel schemas.
• Nested models, validators, and model validators for complex business rules.
• Serialization to and from JSON, dicts, and JSON Schema generation for APIs and config.
• Seamless integration with FastAPI, Django, and other frameworks for request/response validation and settings loading.

Quick Start

Create a simple Pydantic model and validate an input payload to observe automatic type coercion and error messages.
