/// tip | "Tipp"

Die Syntax `{"name", "description"}` erzeugt ein `set` mit diesen zwei Werten.

Äquivalent zu `set(["name", "description"])`.

#### `list`en statt `set`s verwenden

Wenn Sie vergessen, ein `set` zu verwenden, und stattdessen eine `list`e oder ein `tuple` übergeben, wird FastAPI die dennoch in ein `set` konvertieren, und es wird korrekt funktionieren:

যদি আপনি টিউটোরিয়ালের সমস্ত বিষয় পড়ে ফেলে থাকেন এবং টাইপ সম্পর্কে আরও জানতে চান, তবে একটি ভালো রিসোর্স হল [mypy এর "cheat sheet"](https://mypy.readthedocs.io/en/latest/cheat_sheet_py3.html)। এই "cheat sheet" এ আপনি Python টাইপ হিন্ট সম্পর্কে বেসিক থেকে উন্নত লেভেলের ধারণা পেতে পারেন, যা আপনার কোডে টাইপ সেফটি এবং স্পষ্টতা বাড়াতে সাহায্য করবে।

For production you would probably use a migration script that runs before you start your app. 🤓

/// tip

SQLModel will have migration utilities wrapping Alembic, but for now, you can use <a href="https://alembic.sqlalchemy.org/en/latest/" class="external-link" target="_blank">Alembic</a> directly.

### Create a Hero

/// info

If you already went through all the tutorial and came back to see more about types, a good resource is <a href="https://mypy.readthedocs.io/en/latest/cheat_sheet_py3.html" class="external-link" target="_blank">the "cheat sheet" from `mypy`</a>.

/// info | Informação

Se você já passou por todo o tutorial e voltou para ver mais sobre os tipos, um bom recurso é <a href = "https://mypy.readthedocs.io/en/latest/cheat_sheet_py3.html" class = "external-link "target =" _ blank "> a "cheat sheet" do `mypy` </a>.

重要なのは、Pythonの標準的な型を使うことで、（クラスやデコレータなどを追加するのではなく）１つの場所で **FastAPI** が多くの作業を代わりにやってくれているということです。
