```Python
# Bu işe yaramaz, çünkü get_burgers, şu şekilde tanımlandı: async def
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

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

...en vez de `def`:

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

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。🍔🍔

<img src="/img/async/concurrent-burgers/concurrent-burgers-02.png" class="illustration">

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。

The cashier says something to the cook in the kitchen so they know they have to prepare your burgers (even though they are currently preparing the ones for the previous clients).

You pay. 💸

The cashier gives you the number of your turn.

burgers = get_burgers(2)

### 🌅 📡 ℹ

👆 💪 ✔️ 👀 👈 `await` 💪 🕴 ⚙️ 🔘 🔢 🔬 ⏮️ `async def`.

```Python
# Это не заработает, поскольку get_burgers объявлена с использованием async def
burgers = get_burgers(2)
```

---

Если сторонняя библиотека требует вызывать её с ключевым словом `await`,
необходимо писать *функции обработки пути* с использованием `async def`, например:

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

```Python
# Isso não irá funcionar, porquê get_burgers foi definido com: async def
burgers = get_burgers(2)
```

---

Então, se você está usando uma biblioteca que diz que você pode chamá-la com `await`, você precisa criar as *funções de operação de rota* com `async def`, como em:

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

```Python
# This won't work, because get_burgers was defined with: async def
burgers = get_burgers(2)
```

---

따라서, `await`f를 사용해서 호출할 수 있는 라이브러리를 사용한다면, 다음과 같이 `async def`를 사용하는 *경로 작동 함수*를 생성해야 합니다:

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

### 더 세부적인 기술적 사항

`await`가 `async def`를 사용하는 함수 내부에서만 사용이 가능하다는 것을 눈치채셨을 것입니다.

結果を返す前に待機する必要があり、これらの新しいPython機能をサポートする操作がある場合は、次のようにコーディングできます。

```Python
burgers = await get_burgers(2)
```

カギは `await` です。結果を `burgers`に保存する前に、`get_burgers(2)`の処理🕙の完了を待つ⏸必要があることをPythonに伝えます。これでPythonは、その間に (別のリクエストを受信するなど) 何か他のことができる🔀⏯ことを知ります。

`await` が機能するためには、非同期処理をサポートする関数内にある必要があります。これは、`async def` で関数を宣言するだけでよいです:

```Python hl_lines="1"
async def get_burgers(number: int):
    # ハンバーガーを作成するために非同期処理を実行
    return burgers
