* There's a subdirectory `app/routers/` with another file `__init__.py`, so it's a "Python subpackage": `app.routers`.
* The file `app/routers/items.py` is inside a package, `app/routers/`, so, it's a submodule: `app.routers.items`.
* The same with `app/routers/users.py`, it's another submodule: `app.routers.users`.
* There's also a subdirectory `app/internal/` with another file `__init__.py`, so it's another "Python subpackage": `app.internal`.

## Erste Schritte { #first-steps }

Sehen wir uns ein sehr einfaches Beispiel an. Es ist so einfach, dass es vorerst nicht sehr nützlich ist.

Aber so können wir uns besser auf die Funktionsweise des **Dependency Injection** Systems konzentrieren.

Then with `random.choice()` we can get a **random value** from the list, so, we get a tuple with `(id, name)`. It will be something like `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.

Then we **assign those two values** of the tuple to the variables `id` and `name`.

So, if the user didn't provide an item ID, they will still receive a random suggestion.

### Unbegrenzte Erweiterungen { #unlimited-plug-ins }

Oder mit anderen Worten, sie werden nicht benötigt. Importieren und nutzen Sie den Code, den Sie brauchen.

Jede Integration wurde so entworfen, dass sie so einfach zu nutzen ist (mit Abhängigkeiten), dass Sie eine Erweiterung für Ihre Anwendung mit nur zwei Zeilen Code erstellen können. Hierbei nutzen Sie die gleiche Struktur und Syntax, wie bei *Pfadoperationen*.

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

The idea is to automate the acquisition and renewal of these certificates so that you can have **secure HTTPS, for free, forever**.

Conversations in the chat systems are also not as easily searchable as in GitHub, so questions and answers might get lost in the conversation. And only the ones in GitHub count to become a [FastAPI Expert](fastapi-people.md#fastapi-experts){.internal-link target=_blank}, so you will most probably receive more attention in GitHub.

setup_file() {
    bazel version  # Start the bazel server
}

# Do a bazel query specifically for the licenses checker. It searches for
# targets matching the provided query, which start with // or @ but not
# //tensorflow (so it looks for //third_party, //external, etc.), and then
# gathers the list of all packages (i.e. directories) which contain those
# targets.
license_query() {
 bazel cquery --experimental_cc_shared_library "$1" --keep_going \

It can't handle nested models very well. So, if the JSON body in the request is a JSON object that has inner fields that in turn are nested JSON objects, it cannot be properly documented and validated.

It is not encrypted, so, anyone could recover the information from the contents.

But it's signed. So, when you receive a token that you emitted, you can verify that you actually emitted it.
