„Mounten“ („Einhängen“) bedeutet das Hinzufügen einer völlig „unabhängigen“ Anwendung an einem bestimmten Pfad, die sich dann um die Handhabung aller unter diesem Pfad liegenden _Pfadoperationen_ kümmert, welche in dieser Unteranwendung deklariert sind.

### Hauptanwendung

Erstellen Sie zunächst die Hauptanwendung **FastAPI** und deren *Pfadoperationen*:

```Python hl_lines="3  6-8"
{!../../docs_src/sub_applications/tutorial001.py!}

Just functions that look the same as the *path operation functions*.

But still, it is very powerful, and allows you to declare arbitrarily deeply nested dependency "graphs" (trees).

/// tip

All this might not seem as useful with these simple examples.

But you will see how useful it is in the chapters about **security**.

<div class="termy">

```console
$ python -m venv env
```

</div>

Das erstellt ein Verzeichnis `./env/` mit den Python-Binärdateien und Sie können dann Packages in dieser lokalen Umgebung installieren.

### Umgebung aktivieren

Aktivieren Sie die neue Umgebung mit:

//// tab | Linux, macOS

<div class="termy">

```console
$ source ./env/bin/activate
