**ジェネリック型** または **ジェネリクス** と呼びます。

### 型としてのクラス

変数の型としてクラスを宣言することもできます。

例えば、`Person`クラスという名前のクラスがあるとしましょう:

{* ../../docs_src/python_types/tutorial010.py hl[1,2,3] *}


変数の型を`Person`として宣言することができます:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}


そして、再び、すべてのエディタのサポートを得ることができます:

			t.Errorf("Test %d: %s: Expected to fail with error \"%s\", but passed instead.", i, instanceType, testCase.expectedError.Error())
			continue
		}
		// Failed as expected, but does it fail for the expected reason.
		if actualErr != nil && actualErr != testCase.expectedError {
			t.Errorf("Test %d: %s: Expected to fail with error \"%v\", but instead failed with error \"%v\" instead.", i, instanceType, testCase.expectedError, actualErr)

And you don't need to declare anything else for that parameter, so you don't really need to use `Query`.

But you still need to use `Path` for the `item_id` path parameter. And you don't want to use `Annotated` for some reason.

Python will complain if you put a value with a "default" before a value that doesn't have a "default".

But you can re-order them, and have the value without a default (the query parameter `q`) first.

            return;
        }
        if (Features.consumerPom(session.getConfigProperties())) {

       */

        override fun onClosing(
          webSocket: WebSocket,
          code: Int,
          reason: String,
        ) = TODO()

        override fun onClosed(

			t.Errorf("Test %d: %s: Expected to fail with <ERROR> \"%s\", but passed instead.", i+1, instanceType, testCase.expectedError.Error())
		}
		// Failed as expected, but does it fail for the expected reason.
		if actualErr != nil && !testCase.shouldPass {
			if testCase.expectedError.Error() != actualErr.Error() {

In this case, the database session would be held until the response is finished being sent, but if you don't use it, then it wouldn't be necessary to hold it.

Here's how it could look like:
