Start by telling us what problem you’re trying to solve. Often a solution already exists!

from typing import Union

from fastapi import FastAPI, Path, Query

app = FastAPI()


@app.get("/items/{item_id}")
async def read_items(
    item_id: int = Path(title="The ID of the item to get"),
    q: Union[str, None] = Query(default=None, alias="item-query"),
):
    results = {"item_id": item_id}
    if q:
        results.update({"q": q})

 *       values enables it to support an {@linkplain BiMap#inverse inverse view} -- which is another
 *       instance of {@code BiMap}.
 *   <dt>{@link Table}
 *   <dd>A new type, which is similar to {@link java.util.Map}, but which indexes its values by an
 *       ordered pair of keys, a row key and column key.
 *   <dt>{@link Multiset}

Das bedeutet, dass **FastAPI** speziell mit den Editoren getestet wurde, die von 80 % der Python-Entwickler verwendet werden. Und da die meisten anderen Editoren in der Regel ähnlich funktionieren, sollten alle diese Vorteile für praktisch alle Editoren funktionieren.

Auf diese Weise konnte ich die besten Möglichkeiten finden, die Codeverdoppelung so weit wie möglich zu reduzieren, überall Autovervollständigung, Typ- und Fehlerprüfungen, usw. zu gewährleisten.
