환경 변수를 이해하려면 [환경 변수](../environment-variables.md)를 읽어보세요.

///

## 타입과 검증 { #types-and-validation }

이 환경 변수들은 Python 외부에 있으며 다른 프로그램 및 시스템의 나머지 부분(그리고 Linux, Windows, macOS 같은 서로 다른 운영체제와도)과 호환되어야 하므로, 텍스트 문자열만 다룰 수 있습니다.

즉, Python에서 환경 변수로부터 읽어온 어떤 값이든 `str`이 되며, 다른 타입으로의 변환이나 검증은 코드에서 수행해야 합니다.

## Managing hermetic Python

To make sure that TensorFlow's build is reproducible, behaves uniformly across
supported platforms (Linux, Windows, MacOS) and is properly isolated from
specifics of a local system, we rely on hermetic Python (see
[rules_python](https://github.com/bazelbuild/rules_python)) for all build
and test commands executed via Bazel. This means that your system Python
installation will be ignored during the build and Python interpreter itself

 * <ul>
 * <li>windows: All Windows variants</li>
 * <li>win9x: Windows 95, 98, ME, CE</li>
 * <li>winnt: Windows NT variants</li>
 * <li>unix: Unix-like systems (including Linux)</li>
 * <li>mac: macOS (including Darwin)</li>
 * <li>os/2: OS/2 variants</li>
 * <li>netware: Novell NetWare</li>

そのため、アプリケーションが読み取る環境変数で提供するのが一般的です。

/// tip | 豆知識

環境変数について理解するには、[環境変数](../environment-variables.md)を参照してください。

///

## 型とバリデーション { #types-and-validation }

これらの環境変数は Python の外部にあり、他のプログラムやシステム全体（Linux、Windows、macOS といった異なるOSを含む）と互換性が必要なため、文字列テキストのみを扱えます。

つまり、Python で環境変数から読み取られる値はすべて `str` になり、他の型への変換やバリデーションはコードで行う必要があります。

## Pydantic の `Settings` { #pydantic-settings }

因此，通常會透過環境變數提供這些設定，讓應用程式去讀取。

/// tip

若想了解環境變數，你可以閱讀[環境變數](../environment-variables.md)。

///

## 型別與驗證 { #types-and-validation }

這些環境變數只能處理文字字串，因為它們在 Python 之外，必須與其他程式與系統的其餘部分相容（甚至跨作業系統，如 Linux、Windows、macOS）。

這表示在 Python 中自環境變數讀取到的任何值都會是 `str`，而任何轉型成其他型別或驗證都必須在程式碼中完成。

## Pydantic `Settings` { #pydantic-settings }

These environment variables can only handle text strings, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).

That means that any value read in Python from an environment variable will be a `str`, and any conversion to a different type or any validation has to be done in code.

## Pydantic `Settings` { #pydantic-settings }
