 #### Serializing objects
 
-We support the serialization of various Python objects, including Pydantic models, dataclasses, enumerations, file paths, scalar types (strings, integers, floats, and None), dictionaries, various sequence types (lists, sets, frozen sets, generators, tuples, and deques), and others defined [here](https://github.com/aws-powertools/powertools-lambda-python/blob/develop/aws_lambda_powertools/event_handler/openapi/encoders.py#L24).
