return burgers

使用 `async def`，Python 就知道在该函数中，它将遇上 `await`，并且它可以"暂停" ⏸ 执行该函数，直至执行其他操作 🔀 后回来。

当你想调用一个 `async def` 函数时，你必须"等待"它。因此，这不会起作用：

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

---

因此，如果你使用的库告诉你可以使用 `await` 调用它，则需要使用 `async def` 创建路径操作函数 ，如：

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