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():

      print('Found possible Python library paths:\n  %s' %
            '\n  '.join(python_lib_paths))
      default_python_lib_path = python_lib_paths[0]
      python_lib_path = get_input(
          'Please input the desired Python library path to use.  '
          'Default is [{}]\n'.format(python_lib_paths[0]))
      if not python_lib_path:
        python_lib_path = default_python_lib_path
    environ_cp['PYTHON_LIB_PATH'] = python_lib_path

                return true;
            }
        }
        return false;
    }

For the 1.8 release, SIG Scalability focused on automating large cluster
scalability testing in a continuous integration (CI) environment. The SIG
defined a concrete process for scalability testing, created
documentation for the current scalability thresholds, and defined a new set of
Service Level Indicators (SLIs) and Service Level Objectives (SLOs) for the system.
Here's the release [scalability validation report].

   * because caller has previously checked that guardToSkip.isSatisfied() returned false. An
   * optimization for the case that guardToSkip.isSatisfied() may be expensive.
   *
   * <p>We decided against using this method, since in practice, isSatisfied() is likely to be very
   * cheap (typically one field read). Resurrect this method if you find that not to be true.
