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.

In addition to the standard library, there is an active collection of
hundreds of thousands of components (from individual programs and
modules to packages and entire application development frameworks),
available from the Python Package Index.
