## Exemple

### Créez

* Créez un fichier `main.py` avec :

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}

```

C'est une chose différente.

On utilise un deux-points (`:`), et pas un égal (`=`).

Et ajouter des annotations de types ne crée normalement pas de différence avec le comportement qui aurait eu lieu si elles n'étaient pas là.

Maintenant, imaginez que vous êtes en train de créer cette fonction, mais avec des annotations de type cette fois.

- Kubeadm: when a sub command is needed but not provided for a kubeadm command, print a help screen instead of showing a short message. ([#111277](https://github.com/kubernetes/kubernetes/pull/111277), [@chymy](https://github.com/chymy))

    return 1;
  }

  char file_name[100];
  time_t t = time(NULL);
  snprintf(file_name, sizeof(file_name), "test-%d-%ld.txt", getpid(), t);

  size_t length = 2 + strlen(path) + strlen(file_name);
  char* full_path = malloc(length);
  snprintf(full_path, length, "%s/%s", path, file_name);

  TF_WritableFileHandle* h;
  TF_Status* status = TF_NewStatus();

- `kubeadm`: added a new "kubeadm config validate" command that can be used to
  validate any input config file. Use the `--config` flag to pass a config file
  to it. See the command `--help` screen for more information. As a result of adding
  this new command, enhance the validation capabilities of the existing "kubeadm

## Detaylar

`"/static"` ifadesi, bu "alt uygulamanın" "bağlanacağı" alt yolu belirtir. Bu nedenle, `"/static"` ile başlayan her yol, bu uygulama tarafından işlenir.

`directory="static"` ifadesi, statik dosyalarınızı içeren dizinin adını belirtir.

`name="static"` ifadesi, alt uygulamanın **FastAPI** tarafından kullanılacak ismini belirtir.

```JSON
{"item_id":"foo"}
```

## Tip İçeren Yol Parametreleri

Standart Python tip belirteçlerini kullanarak yol parametresinin tipini fonksiyonun içerisinde tanımlayabilirsiniz.
