received from Go. For example:

	package main

	// typedef int (*intFunc) ();
	//
	// int
	// bridge_int_func(intFunc f)
	// {
	//		return f();
	// }
	//
	// int fortytwo()
	// {
	//	    return 42;
	// }
	import "C"
	import "fmt"

	func main() {
		f := C.intFunc(C.fortytwo)
		fmt.Println(int(C.bridge_int_func(f)))
		// Output: 42

## Как это выглядит

Давайте сначала просто воспользуемся кодом и посмотрим, как он работает, а затем детально разберём, что происходит.

## Создание `main.py`

Скопируйте пример в файл `main.py`:

//// tab | Python 3.9+

```Python
{!> ../../docs_src/security/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python

                includeModule('gradle', 'gradle')
            }
        }
    }
}

// We support multiple accepted public api changes JSON files, but "accepted-public-api-changes.json"
// is the "main" one that is also shown in HTML report
def apiChangesJsonDirectory = layout.projectDirectory.dir("src/changes/accepted-changes")
def mainApiChangesJsonFile = apiChangesJsonDirectory.file("accepted-public-api-changes.json")

                            "description": "Successful Response",
                            "content": {"application/json": {"schema": {}}},
                        }
                    },
                    "summary": "Main",
                    "operationId": "main__get",
                }
            },
        },
        "components": {
            "schemas": {
                "Body_create_upload_files_uploadfiles__post": {

        if (link == null) continue; // URL is either invalid or its scheme isn't http/https.
        queue.add(link.newBuilder().fragment(null).build());
      }
    }
  }

  public static void main(String[] args) throws IOException {
    if (args.length != 2) {
      System.out.println("Usage: Crawler <cache dir> <root>");
      return;
    }

    int threadCount = 20;

> Bu projenin geçmişi nedir? Birkaç hafta içinde hiçbir yerden harika bir şeye dönüşmüş gibi görünüyor [...]

İşte o geçmişin bir kısmı.

## Alternatifler

Bir süredir karmaşık gereksinimlere sahip API'lar oluşturuyor (Makine Öğrenimi, dağıtık sistemler, asenkron işler, NoSQL veritabanları vb.) ve farklı geliştirici ekiplerini yönetiyorum.

Bu süreçte birçok alternatifi araştırmak, test etmek ve kullanmak zorunda kaldım.

    try (Response response = client.newCall(request).execute()) {
      // Consume and discard the response body.
      response.body().source().readByteString();
    }
  }

  public static void main(String... args) throws Exception {
    new PrintEventsNonConcurrent().run();
  }

  private static final class PrintingEventListener extends EventListener {
    long callStartNanos;

// reducing the # of rules we need.
//
// BUT netlink lib doesn't support adding things to `list:set` types yet, and current tagged release
// doesn't support creating `list:set` types yet (is in main branch tho).
// So this will actually create 2 underlying ipsets, one for v4 and one for v6
func NewIPSet(name string, v6 bool, deps NetlinkIpsetDeps) (IPSet, error) {
	var err error
	set := IPSet{

然后它会使用你的 **FastAPI** 代码开启服务器，停在断点处，等等。

看起来可能是这样：

如果使用 Pycharm，你可以：

* 打开「运行」菜单。
* 选中「调试...」。
* 然后出现一个上下文菜单。
* 选择要调试的文件（本例中的 `main.py`）。

然后它会使用你的 **FastAPI** 代码开启服务器，停在断点处，等等。

看起来可能是这样：

## Rode o código

Todos os blocos de código podem ser copiados e utilizados diretamente (eles são, na verdade, arquivos Python testados).

Para rodar qualquer um dos exemplos, copie o codigo para um arquivo `main.py`, e inicie o `uvivorn` com:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
