클래스 맛보기
객체 지향 입문
이 장에서 클래스를 살펴보기 전에 확실히 해두어야 할 점이 있는데 바로 이
책에서는 파이썬 클래스의 모든 것을 다루지는 않는다는 사실입니다. 이 장의
목표는 여러분이 컨텍스트 관리 프로토콜을 구현하는 데 필요한 클래스를 만들
만큼 충분히 클래스를 배우는 겁니다.
따라서 객체 지향 프로그래밍(
object
-
oriented
programming
,
OOP
)하면
따라다니는 상속, 다형성 등의 개념은 따로 설명하지 않습니다(파이썬은 두 가지
개념 모두 지원해요). 컨텍스트 관리자를 만들 때는 이들 특성보다는 캡슐화를
사용하기 때문이죠.
위에서 갑자기 등장한 낯선 용어 때문에 당황스럽더라도 걱정하지 마세요.
OOP
관련 지식이나 용어를 몰라도 이 장의 내용을 배우는 데 지장이 없으니까요.

문과 연결하려면 클래스를 만들어야 한다고 설명했습니다.
클래스를 만드는 방법을 살펴보기 전에 예제 클래스를 통해 파이썬 클래스가
어떻게 구성되는지 확인합시다. 클래스를 구현하는 방법을 이해한 다음

있습니다.
