## Pydantic models

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> is a Python library to perform data validation.

You declare the "shape" of the data as classes with attributes.

And each attribute has a type.

  // it doesn't escape this class

and was going on shrinking rapidly:  she soon found out that the
cause of this was the fan she was holding, and she dropped it
hastily, just in time to avoid shrinking away altogether.

`That WAS a narrow escape!' said Alice, a good deal frightened at
the sudden change, but very glad to find herself still in
existence; `and now for the garden!' and she ran with all speed
back to the little door:  but, alas! the little door was shut

 * characters that need to be encoded is different for each component. For example, the path
 * component must escape all of its `?` characters, otherwise it could be interpreted as the
 * start of the URL's query. But within the query and fragment components, the `?` character
 * doesn't delimit anything and doesn't need to be escaped.
