Arguments: meta_schema: the meta schema for the new validator class validators: a mapping from names to callables, where each callable will validate the schema property with the given name. Each callable should take 4 arguments: 1. a validator instance, 2. the value of the property being validated within the instance 3. the instance 4. the schema version: an identifier for the version that this validator class will validate. If provided, the returned validator class will have its ``__name__`` set to include the version, and also will have `jsonschema.validators.validates` automatically called for the given version. type_checker: a type checker, used when applying the :kw:`type` keyword. If unprovided, a `jsonschema.TypeChecker` will be created with a set of default types typical of JSON Schema drafts. format_checker: a format checker, used when applying the :kw:`format` keyword. If unprovided, a `jsonschema.FormatChecker` will be created with a set of default formats typical of JSON Schema drafts. id_of: A function that given a schema, returns its ID. applicable_validators: A function that, given a schema, returns the list of applicable schema keywords and associated values which will be used to validate the instance. This is mostly used to support pre-draft 7 versions of JSON Schema which specified behavior around ignoring keywords if they were siblings of a ``$ref`` keyword. If you're not attempting to implement similar behavior, you can typically ignore this argument and leave it at its default.

A future version will make doing so an error, as the behavior of subclasses isn't guaranteed to stay the same between releases of jsonschema.

Arguments: validator (jsonschema.protocols.Validator): an existing validator class validators (collections.abc.Mapping): a mapping of new validator callables to extend with, whose structure is as in `create`. .. note:: Any validator callables with the same name as an existing one will (silently) replace the old validator callable entirely, effectively overriding any validation done in the "parent" validator class. If you wish to instead extend the behavior of a parent's validator callable, delegate and call it directly in the new validator function by retrieving it using ``OldValidator.VALIDATORS["validation_keyword_name"]``. version (str): a version for the new validator class type_checker (jsonschema.TypeChecker): a type checker, used when applying the :kw:`type` keyword. If unprovided, the type checker of the extended `jsonschema.protocols.Validator` will be carried along. format_checker (jsonschema.FormatChecker): a format checker, used when applying the :kw:`format` keyword. If unprovided, the format checker of the extended `jsonschema.protocols.Validator` will be carried along. Returns: a new `jsonschema.protocols.Validator` class extending the one provided .. note:: Meta Schemas The new validator class will have its parent's meta schema. If you wish to change or extend the meta schema in the new validator class, modify ``META_SCHEMA`` directly on the returned class. Note that no implicit copying is done, so a copy should likely be made before modifying it, in order to not affect the old validator.

If called directly, does not check the store first, but after retrieving the document at the specified URI it will be saved in the store if :attr:`cache_remote` is True. .. note:: If the requests_ library is present, ``jsonschema`` will use it to request the remote ``uri``, so that the correct encoding is detected and used. If it isn't, or if the scheme of the ``uri`` is not ``http`` or ``https``, UTF-8 is assumed.

ValidationError: [2, 3, 4] is too long :func:`~jsonschema.validators.validate` will first verify that the provided schema is itself valid, since not doing so can lead to less obvious error messages and fail in less obvious or consistent ways. If you know you have a valid schema already, especially if you intend to validate multiple instances with the same schema, you likely would prefer using the `jsonschema.protocols.Validator.validate` method directly on a specific validator (e.g. ``Draft202012Validator.validate``). Arguments: instance: The instance to validate schema: The schema to validate with cls (jsonschema.protocols.Validator): The class that will be used to validate the instance. If the ``cls`` argument is not provided, two things will happen in accordance with the specification. First, if the schema has a :kw:`$schema` keyword containing a known meta-schema [#]_ then the proper validator will be used. The specification recommends that all schemas contain :kw:`$schema` properties for this reason. If no :kw:`$schema` property is found, the default validator class is the latest released draft. Any other provided positional and keyword arguments will be passed on when instantiating the ``cls``. Raises: `jsonschema.exceptions.ValidationError`: if the instance is invalid `jsonschema.exceptions.SchemaError`: if the schema itself is invalid .. rubric:: Footnotes ..

Uses the :kw:`$schema` keyword that should be present in the given schema to look up the appropriate validator class. Arguments: schema (collections.abc.Mapping or bool): the schema to look at default: the default to return if the appropriate validator class cannot be determined. If unprovided, the default is to return the latest supported draft. Examples: The :kw:`$schema` JSON Schema keyword will control which validator class is returned: >>> schema = { ... "$schema": "https://json-schema.org/draft/2020-12/schema", ... "type": "integer", ... } >>> jsonschema.validators.validator_for(schema) <class 'jsonschema.validators.Draft202012Validator'> Here, a draft 7 schema instead will return the draft 7 validator: >>> schema = { ... "$schema": "http://json-schema.org/draft-07/schema#", ... "type": "integer", ... } >>> jsonschema.validators.validator_for(schema) <class 'jsonschema.validators.Draft7Validator'> Schemas with no ``$schema`` keyword will fallback to the default argument: >>> schema = {"type": "integer"} >>> jsonschema.validators.validator_for( ... schema, default=Draft7Validator, ... ) <class 'jsonschema.validators.Draft7Validator'> or if none is provided, to the latest version supported. Always including the keyword when authoring schemas is highly recommended. TFz$schemaz�The metaschema specified by $schema was not found.
