# [[Python While Loops]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
A while loop's `else` block runs once when the condition becomes false naturally — but NOT if the loop was exited early via `break`, making else a way to distinguish "loop completed" from "loop was interrupted". [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **`while` loop** — executes statements as long as a condition is true. [S1]
|
||||
- **Manual increment required** — forgetting to update the loop variable causes an infinite loop. [S1]
|
||||
- **`break`** — stops the loop even if the condition is still true. [S1]
|
||||
- **`continue`** — stops the current iteration and continues with the next. [S1]
|
||||
- **`else`** — runs once when the condition becomes false; does NOT run if the loop was stopped by `break`. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **else as "completed without break" signal** — since the else block is skipped specifically when a break fired, it's a built-in way to detect whether a while loop ran to natural completion versus being interrupted. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
- Basic loop: `i = 1; while i < 6: print(i); i += 1`. [S1]
|
||||
- Break: `while i < 6: print(i); if i == 3: break; i += 1` — stops at 3. [S1]
|
||||
- Continue: `while i < 6: i += 1; if i == 3: continue; print(i)` — skips printing 3. [S1]
|
||||
- Else (runs on natural completion): `while i < 6: print(i); i += 1; else: print("i is no longer less than 6")`. [S1]
|
||||
|
||||
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
||||
소스에서 모순되는 정보는 발견되지 않음. else가 break로 종료될 경우 실행되지 않는다는 예외가 명시적으로 강조됨. [S1]
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
현재 발견된 실제 적용 사례가 없습니다 — Python For Loops 챕터에서 동일한 break/continue/else 패턴이 재사용된다. [S1]
|
||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
else runs only if the loop completes without break (Python):
|
||||
```python
|
||||
i = 1
|
||||
while i < 6:
|
||||
print(i)
|
||||
i += 1
|
||||
else:
|
||||
print("i is no longer less than 6")
|
||||
```

## ✅ 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 For Loops]], [[Python If Statement]]
|
||||
- **참조 맥락:** Python 2대 반복문 중 하나 — break/continue/else 패턴이 For Loops에서도 재사용된다.
