Agora você sabe que precisa corrigí-lo, converta `age` em uma string com `str(age)`:

{* ../../docs_src/python_types/tutorial004.py hl[2] *}

## Declarando Tipos

Você acabou de ver o local principal para declarar type hints. Como parâmetros de função.

この関数を見てください。すでに型ヒントを持っています:

{* ../../docs_src/python_types/tutorial003.py hl[1] *}


エディタは変数の型を知っているので、補完だけでなく、エラーチェックをすることもできます。

<img src="https://fastapi.tiangolo.com/img/python-types/image04.png">

これで`age`を`str(age)`で文字列に変換して修正する必要があることがわかります:

{* ../../docs_src/python_types/tutorial004.py hl[2] *}


## 型の宣言

関数のパラメータとして、型ヒントを宣言している主な場所を確認しました。

これは **FastAPI** で使用する主な場所でもあります。

### 単純な型

    /** Current page number for pagination */
    public String currentPageNumber;

    /** Total number of records found */
    public String allRecordCount;

    /** Total number of pages for pagination */
    public String allPageCount;

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

    /** Flag indicating if there is a previous page */

এডিটর ভেরিয়েবলগুলির টাইপ জানার কারণে, আপনি শুধুমাত্র অটোকমপ্লিশনই পান না, আপনি এরর চেকও পান:

<img src="/img/python-types/image04.png">

এখন আপনি জানেন যে আপনাকে এটি ঠিক করতে হবে, `age`-কে একটি স্ট্রিং হিসেবে রূপান্তর করতে `str(age)` ব্যবহার করতে হবে:

{* ../../docs_src/python_types/tutorial004.py hl[2] *}


## টাইপ ঘোষণা

আপনি এতক্ষন টাইপ হিন্ট ঘোষণা করার মূল স্থানটি দেখে ফেলেছেন-- ফাংশন প্যারামিটার হিসেবে।
