[S1] ## 🧠 핵심 개념 (Core concepts) - **`class` keyword** — creates a class, an "object constructor" or blueprint. [S1] - **Instantiation** — `p1 = MyClass()` creates an object from the class. [S1] - **`del`** — deletes an object. [S1] - **Multiple independent objects** — each object from the same class has its own copy of properties. [S1] - **`pass`** — required for an otherwise-empty class body. [S1] ## 📖 세부 내용 (Details) - Basic class: `class MyClass: x = 5`. [S1] - Create object: `p1 = MyClass(); print(p1.x)`. [S1] - Delete object: `del p1`. [S1] - Independent instances: `p1 = MyClass(); p2 = MyClass(); p3 = MyClass()` — each independent. [S1] - Empty class: `class Person: pass`. [S1] ## ⚖️ 모순 및 업데이트 (Contradictions & updates) 소스에서 모순되는 정보는 발견되지 않음. ## 🛠️ 적용 사례 (Applied in summary) 현재 발견된 실제 적용 사례가 없습니다 — 이후 __init__()/self 챕터로 클래스 초기화가 확장된다. [S1] ## 💻 코드 패턴 (Code patterns) Basic class and object (Python): ```python class MyClass: x = 5 p1 = MyClass() print(p1.x) ``` ## ✅ 검증 상태 및 신뢰도 - **상태:** draft - **검증 단계:** conceptual - **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body) - **신뢰 점수:** 0.90 - **중복 검사 결과:** 신규 생성 (New discovery) ## 🔗 지식 그래프 (Knowledge Graph) - **상위/루트:** [[Python Tutorial]] - **관련 개념:** [[Python OOP]], [[Python Class Init Method]], [[Python Class Self Parameter]] - **참조 맥락:** 클래스/객체 기본 개념 — __init__()/self 챕터로 이어진다. ## 📚 출처 (Sources) - [S1] W3Schools — Python Classes and Objects — https://www.w3schools.com/python/python_classes.asp ## 📝 변경 이력 (Change history) - 2026-07-04: Initial draft synthesized from the W3Schools "Python Classes and Objects" page (Astra wiki-curation, P-Reinforce v3.1 format).
