## 協程

**協程** 只是 `async def` 函式所回傳的非常特殊的事物名稱。Python 知道它是一個類似函式的東西，可以啟動它，並且在某個時刻它會結束，但它也可能在內部暫停 ⏸，只要遇到 `await`。

這種使用 `async` 和 `await` 的非同步程式碼功能通常被概括為「協程」。這與 Go 語言的主要特性「Goroutines」相似。

## 結論

讓我們再次回顧之前的句子：

> 現代版本的 Python 支持使用 **"協程"** 的 **`async` 和 `await`** 語法來寫 **"非同步程式碼"**。

現在應該能明白其含意了。✨

這些就是驅動 FastAPI（通過 Starlette）運作的原理，也讓它擁有如此驚人的效能。
