valideer – lightweight data validation and adaptation Python library

valideer is a lightweight data validation and adaptation library for Python.

It supports Python 3.

valideer is free and open source software.

Features include:

  • Supports both validation (check if a value is valid) and adaptation (convert a valid input to an appropriate output).
  • Succinct: validation schemas can be specified in a declarative and extensible mini “language”; no need to define verbose schema classes upfront. A regular Python API is also available if the compact syntax is not your cup of tea.
  • Batteries included: validators for most common types are included out of the box.
  • Extensible: New custom validators and adaptors can be easily defined and registered.
  • Informative, customizable error messages: Validation errors include the reason and location of the error.
  • Agnostic: not tied to any particular framework or application domain (e.g. Web form validation).
  • Well tested: Extensive test suite with 100% coverage.
  • Production ready: Used for validating every access to the Podio API.
