Documentation for the python Generator

METADATA

Property	Value	Notes
generator name	python	pass this to the generate command after -g
generator stability	STABLE
generator type	CLIENT
generator language	Python
generator language version	>=3.7
generator default templating engine	handlebars
helpTxt	Generates a Python client library Features in this generator: - type hints on endpoints and model creation - model parameter names use the spec defined keys and cases - robust composition (oneOf/anyOf/allOf/not) where payload data is stored in one instance only - endpoint parameter names use the spec defined keys and cases - inline schemas are supported at any location including composition - multiple content types supported in request body and response bodies - run time type checking - Sending/receiving decimals as strings supported with type:string format: number -> DecimalSchema - Sending/receiving uuids as strings supported with type:string format: uuid -> UUIDSchema - quicker load time for python modules (a single endpoint can be imported and used without loading others) - all instances of schemas dynamically inherit from all matching schemas so one can use isinstance to check if validation passed - composed schemas with type constraints supported (type:object + oneOf/anyOf/allOf) - schemas are not coerced/cast. For example string + date are both stored as string, and there is a date accessor - 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

CONFIG OPTIONS

These options may be applied as additional-properties (cli) or configOptions (plugins). Refer to configuration docs for more details.

Option	Description	Values	Default
generateSourceCodeOnly	Specifies that only a library source code is to be generated.		false
hideGenerationTimestamp	Hides the generation timestamp when files are generated.		true
library	library template (sub-template) to use: urllib3		urllib3
nonCompliantUseDiscriminatorIfCompositionFails	When true, If the payload fails to validate against composed schemas (allOf/anyOf/oneOf/not) and a discriminator is present, then ignore the composition validation errors and attempt to use the discriminator to validate the payload.<br />Note: setting this to true makes the generated client not comply with json schema because it ignores composition validation errors. Please consider making your schemas more restrictive rather than setting this to true. You can do that by:<ul><li>defining the propertyName as an enum with only one value in the schemas that are in your discriminator map</li><li>setting additionalProperties: false in your schemas</li></ul>	true If composition fails and a discriminator exists, the composition errors will be ignored and validation will be attempted with the discriminator false Composition validation must succeed. Discriminator validation must succeed.	false
packageName	python package name (convention: snake_case).		openapi_client
packageUrl	python package URL.		null
packageVersion	python package version.		1.0.0
projectName	python project name in setup.py (e.g. petstore-api).		null
recursionLimit	Set the recursion limit. If not set, use the system default value.		null
useInlineModelResolver	use the inline model resolver, if true inline complex models will be extracted into components and $refs to them will be used		false
useNose	use the nose test framework		false
