Most of the code is actually the same.

So, we are going to focus only on the differences.

## File structure

Let's say you have a directory named `my_super_project` that contains a sub-directory called `sql_app` with a structure like this:

```
.
└── sql_app
    ├── __init__.py
    ├── crud.py
    ├── database.py
    ├── main.py
    └── schemas.py
```

{!../../../docs_src/python_types/tutorial001.py!}
```

### 編集

これはとても簡単なプログラムです。

しかし、今、あなたがそれを一から書いていたと想像してみてください。

パラメータの準備ができていたら、そのとき、関数の定義を始めていたことでしょう...

しかし、そうすると「最初の文字を大文字に変換するあのメソッド」を呼び出す必要があります。

それは`upper`でしたか？`uppercase`でしたか？それとも`first_uppercase`？または`capitalize`？

そして、古くからプログラマーの友人であるエディタで自動補完を試してみます。

関数の最初のパラメータ`first_name`を入力し、ドット(`.`)を入力してから、`Ctrl+Space`を押すと補完が実行されます。

しかし、悲しいことに、これはなんの役にも立ちません:
