# Introduction aux Types Python

Python supporte des annotations de type (ou *type hints*) optionnelles.

Ces annotations de type constituent une syntaxe spéciale qui permet de déclarer le <abbr title="par exemple : str, int, float, bool">type</abbr> d'une variable.

En déclarant les types de vos variables, cela permet aux différents outils comme les éditeurs de texte d'offrir un meilleur support.

    /** Total number of records across all pages. */
    private int allRecordCount;

    /** Total number of pages. */
    private int allPageCount;

    /** Flag indicating if there is a previous page. */
    private boolean existPrePage;

    /** Flag indicating if there is a next page. */
    private boolean existNextPage;

    /** List of page numbers for pagination navigation. */
    private List<Integer> pageNumberList;

        assertEquals(expectedType, info.getType());
    }

    @Test
    @DisplayName("Test getType with hidden flag")
    void testGetTypeWithHiddenFlag() {
        // Hidden flag (0x80000000) should be masked out
        int hiddenPrinterType = 0x80000001; // Hidden printer
        SmbShareInfo info = new SmbShareInfo(TEST_NET_NAME, hiddenPrinterType, TEST_REMARK);

            "type": "type_error.integer"
        }
    ]
}
```

из-за того, что параметр пути `item_id` имеет значение `"foo"`, которое не является типом  `int`.

Та же ошибка возникнет, если вместо `int` передать `float` , например: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>

**FastAPI** обеспечивает проверку типов, используя всё те же определения типов.
