С **FastAPI** вы получаете все возможности **Starlette** (так как FastAPI — это всего лишь Starlette на стероидах):

* Серьёзно впечатляющая производительность. Это <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">один из самых быстрых фреймворков на Python, наравне с **NodeJS** и **Go**</a>.
* Поддержка **WebSocket**.
* Фоновые задачи в том же процессе.

// In represents the RHS of an IN expression. The RHS can be a list-literal

// expression (as in `8.5 IN s.nested[*][*]`). Specifically, it cannot be an
// `Expression` as an expression can never evaluate to a list.

		// Do this by swapping next and i

Isso ocorre por que, por padrão, o FastAPI irá verificar cada item dentro do dicionário e garantir que ele seja serializável para JSON, utilizando o mesmo[Codificador Compatível com JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado no tutorial. Isso permite que você retorne **objetos abstratos**, como modelos do banco de dados, por exemplo.

		if testCase.copySourceHeader != "" {
			if values.Encode() != "" && !strings.Contains(testCase.copySourceHeader, "?") {
				req.Header.Set("X-Amz-Copy-Source", testCase.copySourceHeader+"?"+values.Encode())
			} else {
				req.Header.Set("X-Amz-Copy-Source", testCase.copySourceHeader)
			}
		}
		if testCase.copyModifiedHeader != "" {

通過 **FastAPI** 你可以獲得所有 **Starlette** 的特性（FastAPI 就像加強版的 Starlette）：

* 性能極其出色。它是 <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">Python 可用的最快框架之一，和 **NodeJS** 及 **Go** 相當</a>。
* **支援 WebSocket**。
* 能在行程內處理背景任務。
* 支援啟動和關閉事件。
* 有基於 HTTPX 的測試用戶端。
* 支援 **CORS**、GZip、靜態檔案、串流回應。
