파이썬 표준 라이브러리
**********************

파이썬 언어 레퍼런스 는 파이썬 언어의 정확한 문법과 의미를 설명하고 있
지만, 이 라이브러리 레퍼런스 설명서는 파이썬과 함께 배포되는 표준 라이
브러리를 설명합니다. 또한, 파이썬 배포판에 일반적으로 포함되어있는 선
택적 구성 요소 중 일부를 설명합니다.

파이썬의 표준 라이브러리는 매우 광범위하며, 아래 나열된 긴 목차에 표시
된 대로 다양한 기능을 제공합니다. 라이브러리에는 일상적인 프로그래밍에
서 발생하는 많은 문제에 대한 표준적인 해결책을 제공하는 파이썬으로 작
성된 모듈뿐만 아니라, 파일 I/O와 같은 시스템 기능에 액세스하는 (C로 작
성된) 내장 모듈들이 포함됩니다 (이 모듈들이 없다면 파이썬 프로그래머가
액세스할 방법은 없습니다). 이 모듈 중 일부는 플랫폼 관련 사항을 플랫폼
중립적인 API들로 추상화시킴으로써, 파이썬 프로그램의 이식성을 권장하고
개선하도록 명시적으로 설계되었습니다.

윈도우 플랫폼용 파이썬 설치 프로그램은 일반적으로 전체 표준 라이브러리
를 포함하며 종종 많은 추가 구성 요소도 포함합니다. 유닉스와 같은 운영
체제의 경우, 파이썬은 일반적으로 패키지 모음으로 제공되기 때문에, 운영
체제와 함께 제공되는 패키지 도구를 사용하여 선택적 구성 요소의 일부 또
는 전부를 구해야 할 수 있습니다.

표준 라이브러리 외에도, 수십만 가지 컴포넌트(개별 프로그램과 모듈부터
패키지 및 전체 응용 프로그램 개발 프레임워크까지)로 구성된 활발한 모음
이 있는데, 파이썬 패키지 색인 에서 얻을 수 있습니다.
