"""
|
|
An implementation of JSON Schema for Python.
|
|
|
|
The main functionality is provided by the validator classes for each of the
|
|
supported JSON Schema versions.
|
|
|
|
Most commonly, `jsonschema.validators.validate` is the quickest way to simply
|
|
validate a given instance under a schema, and will create a validator
|
|
for you.
