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.

## Pydantic `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。

## 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 }

All source code in Gradle is written to target one or more of these runtimes.
Most source code targets the daemon and the remaining code either targets a single runtime, for example the Gradle client, or is shared across multiple runtimes.

## Composition by architecture modules

Each [architecture module and platform](platforms.md) can contribute code to any of the runtimes.
Not every module contributes to every runtime.

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。

## 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 }

import (
	. "bytes"
	"syscall"
	"testing"
)

// This file tests the situation where byte operations are checking
// data very near to a page boundary. We want to make sure those
// operations do not read across the boundary and cause a page
// fault where they shouldn't.

// These tests run only on linux. The code being tested is
// not OS-specific, so it does not need to be tested on all
// operating systems.
