### 型としてのクラス { #classes-as-types }

変数の型としてクラスを宣言することもできます。

名前を持つ `Person` クラスがあるとしましょう:

{* ../../docs_src/python_types/tutorial010_py310.py hl[1:3] *}

変数を `Person` 型として宣言できます:

        assertFalse(testClient.calledMethods.contains("switchAliases"));
    }

    // ==========================================================================
    // getDocumentCount and getAliasCount edge cases
    // ==========================================================================

     * Desired behaviour is to match the results of applying the naive mean formula. In particular,
     * the update formula can subtract infinities in cases where the naive formula would add them.
     *
     * Consequently:
     * 1. If the previous mean is finite and the new value is non-finite then the new mean is that
     *    value (whether it is NaN or infinity).
