The most important part is that when you call `python`, that is the exact "`python`" that will be executed.

So, you can confirm if you are in the correct virtual environment.

/// tip

It's easy to activate one virtual environment, get one Python, and then **go to another project**.

* Нажмите кнопку «Try it out», это позволит вам заполнить параметры и напрямую взаимодействовать с API:

 *  New: `MultipartReader` is a streaming decoder for [MIME multipart (RFC 2045)][rfc_2045]
    messages. It complements `MultipartBody` which is our streaming encoder.

    ```kotlin
    val response: Response = call.execute()
    val multipartReader = MultipartReader(response.body!!)

    multipartReader.use {
      while (true) {
        val part = multipartReader.nextPart() ?: break
        process(part.headers, part.body)

* Klicken Sie dann auf den Button „Execute“, die Benutzeroberfläche wird mit Ihrer API kommunizieren, die Parameter senden, die Ergebnisse erhalten und sie auf dem Bildschirm anzeigen:

                            .maxSymbolTermSize(maxSymbolTermSize)
                            .duplicateTermRemoved(replaceDuplication)
                            .spaceChars(spaceChars)
                            .execute();
                }
                return ReaderUtil.readText(reader);
            }
        } catch (final TikaException e) {
            throw e;

Agora, execute sua aplicação:

<div class="termy">

```console
$ fastapi dev app/main.py

* "Try it out" 버튼을 클릭하면, 매개변수를 채울 수 있게 해주고 직접 API와 상호작용 할 수 있습니다:

![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-04-swagger-03.png)

* 그러고 나서 "Execute" 버튼을 누르면, 사용자 인터페이스는 API와 통신하고 매개변수를 전송하며 그 결과를 가져와서 화면에 표시합니다:

### 대안 API 문서 업그레이드

* Click on the button "Try it out", it allows you to fill the parameters and directly interact with the API:

![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-04-swagger-03.png)

* Then click on the "Execute" button, the user interface will communicate with your API, send the parameters, get the results and show them on the screen:

    `BufferedSink` and a `ResponseBody` as an Okio `BufferedSource`. Standard
    `InputStream` and `OutputStream` access is also available.

 *  **New Call and Callback types** execute requests and receive their
    responses. Both types of calls can be canceled via the `Call` or the
    `OkHttpClient`.

 *  **URLConnection support has moved to the okhttp-urlconnection module.**
