This solved having to write YAML (another syntax) inside of Python docstrings.

This combination of Flask, Flask-apispec with Marshmallow and Webargs was my favorite backend stack until building **FastAPI**.

Using it led to the creation of several Flask full-stack generators. These are the main stacks I (and several external teams) have been using up to now:

                                    <span class="font-weight-bold col-sm-3 text-sm-right col-form-label"><la:message
                                            key="labels.user_favorite_enabled"/></span>
                                    <div class="form-inline col-sm-9">
                                        <la:errors property="userFavorite"/>

                **Example**

                ```python
                from fastapi import FastAPI

                app = FastAPI(summary="Deadpond's favorite app. Nuff said.")
                ```
                """
            ),
        ] = None,

beginning to feel a little worried.

  `Just about as much right,' said the Duchess, `as pigs have to fly;
and the m--'

  But here, to Alice's great surprise, the Duchess's voice died
away, even in the middle of her favourite word `moral,' and the
arm that was linked into hers began to tremble.  Alice looked up,
and there stood the Queen in front of them, with her arms folded,
frowning like a thunderstorm.
