 | helpTxt | Generates a Python client library<br /><br />Features in this generator:<br />- type hints on endpoints and model creation<br />- model parameter names use the spec defined keys and cases<br />- robust composition (oneOf/anyOf/allOf/not) where payload data is stored in one instance only<br />- endpoint parameter names use the spec defined keys and cases<br />- inline schemas are supported at any location including composition<br />- multiple content types supported in request body and response bodies<br />- run time type checking<br />- Sending/receiving decimals as strings supported with type:string format: number -> DecimalSchema<br />- Sending/receiving uuids as strings supported with type:string format: uuid -> UUIDSchema<br />- quicker load time for python modules (a single endpoint can be imported and used without loading others)<br />- all instances of schemas dynamically inherit from all matching schemas so one can use isinstance to check if validation passed<br />- composed schemas with type constraints supported (type:object + oneOf/anyOf/allOf)<br />- schemas are not coerced/cast. For example string + date are both stored as string, and there is a date accessor<br />    - Exceptions: int/float is stored as Decimal, When receiving data from headers it will start as str and may need to be cast for example to int | |
