Pydantic - Nested Models, JSON Schema and Auto-Generating Models with datamodel-code-generator

In this video, we dive further into the Pydantic library in Python. This is based on the following blog post:
https://bugbytes.io/posts/pydantic-nested-models-and-json-schemas/

We'll learn a number of things, including:

* How to define nested Pydantic models, forming parent-child relationships that allow us to model complex data that contains relationships.
* Using typing.Literal to constrain values on a field
* Defining default values for fields
* Generating JSON Schema from Pydantic models
* Auto-generating Pydantic models from JSON Schema definitions
