return burgers
```

使用 `async def`，Python 知道在該函式內需要注意 `await`，並且它可以「暫停」 ⏸ 執行該函式，然後執行其他任務 🔀 後回來。

當你想要呼叫 `async def` 函式時，必須使用「await」。因此，這樣寫將無法運行：

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

如果你正在使用某個函式庫，它告訴你可以使用 `await` 呼叫它，那麼你需要用 `async def` 定義*路徑操作函式*，如：

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

                return true;
            }
        }
        return false;
    }
