私たち人間は常に**間違い**を犯します。ソフトウェアには、ほとんど常に**バグ**があらゆる箇所に隠されています。🐛

### 小さなエラーは自動的に処理される

FastAPIでWeb APIを構築する際に、コードにエラーがある場合、FastAPIは通常、エラーを引き起こした単一のリクエストにエラーを含めます。🛡

クライアントはそのリクエストに対して**500 Internal Server Error**を受け取りますが、アプリケーションは完全にクラッシュするのではなく、次のリクエストのために動作を続けます。

### 重大なエラー - クラッシュ

しかしながら、**アプリケーション全体をクラッシュさせるようなコードを書いて**UvicornとPythonをクラッシュさせるようなケースもあるかもしれません。💥

もし `philosophers-stone` （賢者の石）の仮想環境を無効化していないと、`python` を実行したとき、 ターミナルは `philosophers-stone` （賢者の石）のPythonを使用しようとします。

If any of these <code>#define</code> names are ambiguous (for example,
a struct with a <code>_size</code> field), <code>#include
"go_asm.h"</code> will fail with a "redefinition of macro" error.

For garbage collection to run correctly, the runtime must know the
location of pointers in all global data and in most stack frames.

was quite impossible to say whether the blows hurt it or not.

  `Oh, PLEASE mind what you're doing!' cried Alice, jumping up
and down in an agony of terror.  `Oh, there goes his PRECIOUS
nose'; as an unusually large saucepan flew close by it, and very
nearly carried it off.
