# [[Python OOP]]

## 🎯 한 줄 통찰 (One-line insight)
OOP organizes code around classes (blueprints) and objects (instances), directly serving the DRY principle by letting repeated structure live in one class definition instead of scattered code. [S1]

## 🧠 핵심 개념 (Core concepts)
- **OOP** — Object-Oriented Programming; Python structures code using classes and objects. [S1]
- **Advantages** — clear structure, easier maintenance/reuse/debugging, DRY code, reusable applications with less code. [S1]
- **Class** — defines what an object should look like (a blueprint). [S1]
- **Object** — an instance created based on a class. [S1]
- **DRY principle** — avoid writing the same code more than once; move repeated code into functions/classes. [S1]

## 📖 세부 내용 (Details)
이 문서는 OOP 챕터군 전체의 개론이며, __init__()/self/properties/methods/inheritance/polymorphism/encapsulation/inner classes가 이어지는 전용 챕터에서 다뤄진다. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 이 개론 뒤에 OOP 핵심 개념 8개 챕터가 이어진다. [S1]

## 💻 코드 패턴 (Code patterns)
소스에 코드 예시 없음 (개론 페이지, 각 OOP 챕터에서 코드 제공).
