Data validation and settings management using python type hinting. Define how data should be in pure, canonical python; validate it with pydantic. PEP 484 introduced type hinting into python 3.5, PEP 526 extended that with syntax for variable annotation in python 3.6. pydantic uses those annotations to validate that untrusted data takes the form you want. There’s also support for an extension to dataclasses where the input data is validated. #python #validation #library #pub
