# [[Python Pass Statement]]

## 🎯 한 줄 통찰 (One-line insight)
Python cannot have a truly empty code block — a comment alone raises an IndentationError — so `pass` exists as an actual (no-op) statement that satisfies the syntax requirement while doing nothing. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`pass`** — a null operation; nothing happens when it executes; a placeholder. [S1]
- **Why needed** — if/for/function/class blocks cannot be syntactically empty in Python. [S1]
- **Common uses** — sketching structure before implementing logic, satisfying syntax when no action is needed, placeholders during development, empty functions/classes planned for later. [S1]
- **`pass` vs. comments** — a comment is ignored entirely by Python and does NOT satisfy the "block needs a statement" requirement; `pass` does. [S1]
- **Works in other contexts too** — loops, functions, classes, not just if statements. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Comment-only block is a common beginner error** — `if score > 90: # comment` with no actual statement raises `IndentationError`, since comments aren't statements — `pass` is the fix. [S1]

## 📖 세부 내용 (Details)
- Basic pass: `if b > a: pass`. [S1]
- Comment-only block fails: `if score > 90: # This is excellent` alone raises IndentationError. [S1]
- Fixed with pass: `if score > 90: pass # This is excellent`. [S1]
- In a function stub: `def calculate_discount(price): pass  # TODO: Implement discount logic`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 함수/클래스의 스텁(stub) 구현에 표준적으로 쓰이는 패턴이다. [S1]

## 💻 코드 패턴 (Code patterns)
pass as a function stub placeholder (Python):
```python
def calculate_discount(price):
    pass  # TODO: Implement discount logic
```

## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** conceptual
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
- **신뢰 점수:** 0.88
- **중복 검사 결과:** 신규 생성 (New discovery)

## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[Python Tutorial]]
- **관련 개념:** [[Python If Statement]], [[Python For Loops]], [[Python Functions]]
- **참조 맥락:** 빈 블록이 필요한 모든 곳(if/for/함수/클래스)에서 재사용되는 플레이스홀더.
