$(document).on('input', '.filter-search-input', function() {
            var query = $(this).val().toLowerCase();
            $(this).closest('.filter-dropdown-menu').find('.filter-check-item').each(function() {
                var label = $(this).find('.filter-check-label').text().toLowerCase();

```

Use the scope `"function"` when they should run the exit code after the response data is generated but before the response is sent back to the client.

```python
from typing import Annotated

		vID, err := uuid.Parse(fi.TierFreeVersionID())
		if err != nil {
			panic(fmt.Errorf("Invalid Tier Object delete marker versionId %s %v", fi.TierFreeVersionID(), err))
		}
		freeEntry := xlMetaV2Version{Type: DeleteType, WrittenByVersion: globalVersionUnix}
		freeEntry.DeleteMarker = &xlMetaV2DeleteMarker{
			VersionID: vID,

在這個例子中，`str` 是傳給 `list` 的型別參數。

///

這表示：「變數 `items` 是一個 `list`，而這個清單中的每個元素都是 `str`」。

這麼做之後，你的編輯器甚至在處理清單裡的項目時也能提供支援：

<img src="/img/python-types/image05.png">

沒有型別時，幾乎不可能做到這點。

請注意，變數 `item` 是清單 `items` 中的一個元素。

即便如此，編輯器仍然知道它是 `str`，並提供相應的支援。

#### Tuple 與 Set { #tuple-and-set }

你也可以用相同方式來宣告 `tuple` 與 `set`：

{* ../../docs_src/python_types/tutorial007_py310.py hl[1] *}

這代表：

│   └── main.py
```

No arquivo `main.py` você tem sua aplicação **FastAPI**:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

### Arquivo de teste { #testing-file }

Então você poderia ter um arquivo `test_main.py` com seus testes. Ele poderia estar no mesmo pacote Python (o mesmo diretório com um arquivo `__init__.py`):

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py

                        </h1>
                    </div>
                    <div class="col-sm-6">
                        <ol class="breadcrumb float-sm-right">
                            <li class="breadcrumb-item active"><la:link href="/admin/elevateword">
                                <la:message key="labels.elevate_word_link_list"/>
                            </la:link></li>
                        </ol>
                    </div>

		}

		if i > 3 {
			// Simulate transition of a version
			transfi := fi
			transfi.TransitionStatus = lifecycle.TransitionComplete
			transfi.TransitionTier = "MINIO-TIER"
			transfi.TransitionedObjName = mustGetUUID()
			xl.DeleteVersion(transfi)

			fi.SetTierFreeVersionID(mustGetUUID())
			// delete this version leading to a free version
			xl.DeleteVersion(fi)

                        </h1>
                    </div>
                    <div class="col-sm-6">
                        <ol class="breadcrumb float-sm-right">
                            <li class="breadcrumb-item active"><la:link href="/admin/crawlinginfo">
                                <la:message key="labels.crawling_info_title"/>
                            </la:link></li>
                        </ol>
                    </div>

## Eine benutzerdefinierte `Response` zurückgeben { #returning-a-custom-response }

Das obige Beispiel zeigt alle Teile, die Sie benötigen, ist aber noch nicht sehr nützlich, da Sie das `item` einfach direkt hätten zurückgeben können, und **FastAPI** würde es für Sie in eine `JSONResponse` einfügen, es in ein `dict` konvertieren, usw. All das standardmäßig.
