 Then we also have Python files. Most of these are generated directly from `metadata.json` - for example `Checklist.py` is a class definition corresponding to the Checklist React component, and if you look inside it you’ll see it inherits from the `dash.development.base_component.Component` class, it has a docstring listing all props and their types in Python notation (instead of “array of objects”, it says “list of dicts”), and it has a constructor that ensures you can only create it with appropriate props. Then there are some Python files that are NOT generated, but copied from https://github.com/plotly/dash-core-components/tree/master/dash_core_components_base - `__init__.py` collects all the component classes and explicitly lists all the browser assets in `_js_dist` and possibly `_css_dist`.

 - Provide a natural way for users of this language to create components as data structures, keeping in mind that components may be nested inside the children prop of some other components, and most props are optional.
 - To the extent that we can help users with built-in documentation and IDE auto-completion, we should try to do that.
 - When requested by the framework, the component must serialize to JSON. This looks like:
