jsonschema is a Python library that validates Python objects (dictionaries, lists, etc.) against the JSON Schema specification. Calling validate(instance, schema) raises a ValidationError for data that does not match the schema and tells you which value at which path failed. Multiple specification versions can be selected through Validator classes, and it is widely used to check configuration files and API input.
