你和你的恋人一起去快餐店，你排队在后面，收银员从你前面的人接单。😍

然后轮到你了，你为你的恋人和你选了两个非常豪华的汉堡。🍔🍔

收银员对厨房里的厨师说了一些话，让他们知道他们必须为你准备汉堡（尽管他们目前正在为之前的顾客准备汉堡）。

你付钱了。 💸

收银员给你轮到的号码。

burgers = get_burgers(2)

Bu nedenle, size onu `await` ile çağırabileceğinizi söyleyen bir kitaplık kullanıyorsanız, onu `async def` ile tanımlanan *path fonksiyonu* içerisinde kullanmanız gerekir, örneğin:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

### Daha fazla teknik detay

```Python hl_lines="1"
async def get_burgers(number: int):
    # Do some asynchronous stuff to create the burgers
    return burgers
```

...`def`를 사용하는 대신:

```Python hl_lines="2"
# This is not asynchronous
def get_sequential_burgers(number: int):
    # Do some sequential stuff to create the burgers
    return burgers
```

```Python
# get_burgersはasync defで定義されているので動作しない
burgers = get_burgers(2)
```

---

したがって、 `await` で呼び出すことができるライブラリを使用している場合は、次のように `async def` を使用して、それを使用する*path operation 関数*を作成する必要があります:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

### より発展的な技術詳細

`await` は `async def` で定義された関数内でのみ使用できることがわかったかと思います。

Brandenburg. Das Museum setzt sich mit der Sozial- und Technikgeschichte des alten Glasmacher-Ortes auseinander.
Eine Ausstellung über den Erfinder der Thermoskanne Reinhold Burger ist zu besichtigen. Im Dorf selbst haben sich
zahlreiche Handwerker und Gewerbetreibende niedergelassen, denen über die Schulter geschaut bzw. mitgemacht
werden kann.
