pydantic

Pydantic is a powerful Python library that makes it easy to define data structures with type annotations and then validate instances of those structures against those definitions. It’s built on top of the typing module and uses Pydantic’s own schema language, which allows you to specify data types, constraints, and default values for your data models. This is incredibly useful in building APIs, ensuring data integrity, and streamlining data processing pipelines. Unlike traditional validation libraries, Pydantic leverages Python’s type hints extensively, providing a seamless integration with existing codebases. It also handles serialization and deserialization efficiently.
