Vamos supor que a estrutura de arquivos do seu projeto se pareça com isso:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
```

Agora crie um diretório para armazenar esses arquivos estáticos.

Sua nova estrutura de arquivos poderia se parecer com isso:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static/
```

### Baixe os arquivos

import uuid

import pytest
from fastapi import FastAPI
from fastapi.testclient import TestClient
from pydantic import BaseModel

from .utils import needs_pydanticv1, needs_pydanticv2


class MyUuid:
    def __init__(self, uuid_string: str):
        self.uuid = uuid_string

    def __str__(self):
        return self.uuid

    @property  # type: ignore
    def __class__(self):
        return uuid.UUID

    @property

### Project file structure

Let's say your project file structure looks like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
```

Now create a directory to store those static files.

Your new file structure could look like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static/
```

### Download the files

Nehmen wir an, die Dateistruktur Ihres Projekts sieht folgendermaßen aus:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
```

Erstellen Sie jetzt ein Verzeichnis zum Speichern dieser statischen Dateien.

Ihre neue Dateistruktur könnte so aussehen:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static/
```

### Die Dateien herunterladen

## Klassen als Abhängigkeiten

Möglicherweise stellen Sie fest, dass Sie zum Erstellen einer Instanz einer Python-Klasse die gleiche Syntax verwenden.

Zum Beispiel:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In diesem Fall ist `fluffy` eine Instanz der Klasse `Cat`.

Und um `fluffy` zu erzeugen, rufen Sie `Cat` auf.

⚖️

```Python
something(some_argument, some_keyword_argument="foo")
```

⤴️ ⚫️ "🇧🇲".
