    Convert any object to something that can be encoded in JSON.

    This is used internally by FastAPI to make sure anything you return can be
    encoded as JSON before it is sent to the client.

    You can also use it yourself, for example to convert objects before saving them
    in a database that supports only JSON.

So, even with the code above that doesn't use Pydantic explicitly, FastAPI is using Pydantic to convert those standard dataclasses to Pydantic's own flavor of dataclasses.

And of course, it supports the same:

* data validation
* data serialization
* data documentation, etc.

Use the formal grammar (use «Sie» instead of «Du»).


### Quotes

1) Convert neutral double quotes («"») and English double typographic quotes («“» and «”») to German double typographic quotes («„» and «“»). Convert neutral single quotes («'») and English single typographic quotes («‘» and «’») to German single typographic quotes («‚» and «‘»). Do NOT convert «`"» to «„», do NOT convert «"`» to «“».

Examples:

    Source (English):

        «««

                                        },
