            }
        };

        // Test with new entraid.use.ds key set to false
        systemPropMap.put("entraid.use.ds", "false");
        assertFalse(fessConfig.isEntraIdUseDomainServices());

        // Test with new entraid.use.ds key set to true

没有类型的话，这几乎是不可能做到的。

注意，变量 `item` 是列表 `items` 中的一个元素。

即便如此，编辑器仍然知道它是 `str`，并为此提供支持。

#### 元组和集合 { #tuple-and-set }

声明 `tuple` 和 `set` 的方式类似：

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

这表示：

* 变量 `items_t` 是一个含有 3 个元素的 `tuple`，分别是一个 `int`、另一个 `int`，以及一个 `str`。
* 变量 `items_s` 是一个 `set`，其中每个元素的类型是 `bytes`。

#### 字典 { #dict }

定义 `dict` 时，需要传入 2 个类型参数，用逗号分隔。

第一个类型参数用于字典的键。

    public void test_getMessage() {
        // Test that getMessage returns null (no message set in constructor)
        UserRoleLoginException exception = new UserRoleLoginException(RootAction.class);
        assertNull(exception.getMessage());
    }

    @Test
    public void test_getCause() {
        // Test that getCause returns null (no cause set in constructor)

## OpenAPI operationId { #openapi-operationid }

/// warning

If you are not an "expert" in OpenAPI, you probably don't need this.

///

You can set the OpenAPI `operationId` to be used in your *path operation* with the parameter `operation_id`.

You would have to make sure that it is unique for each operation.
