この情報は、[Virtual Environments](virtual-environments.md) について学ぶ際にも役立ちます。

## まとめ

これで、**環境変数**とは何か、Pythonでどのように使用するかについて、基本的な理解が得られたはずです。

環境変数についての詳細は、<a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia: Environment Variable</a> を参照してください。

環境変数の用途や適用方法が最初は直感的ではないかもしれませんが、開発中のさまざまなシナリオで繰り返し登場します。そのため、基本を知っておくことが重要です。
