docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

+# [[Python Match]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+match (Python's switch-like statement) selects one block by comparing a value against each `case`, with `_` as a catch-all default, `|` to combine multiple values in one case, and an optional `if` guard for extra conditions. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`match` statement** — replaces long if/elif chains; selects one of many code blocks. [S1]
+- **Syntax** — `match expression: case x: ... case y: ... case z: ...`. [S1]
+- **Evaluation** — the expression is evaluated once, then compared against each case in order. [S1]
+- **`_` default case** — matches anything; must be placed LAST to act as a true default (since it always matches). [S1]
+- **`|` combine values** — `case 1 | 2 | 3:` matches any of the listed values in one case. [S1]
+- **`if` guard** — `case 1 | 2 | 3 if month == 4:` adds an extra condition to a case. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **`_` must be last** — since `_` always matches, placing it before other cases would make those cases unreachable — its position enforces its role as fallback. [S1]
+
+## 📖 세부 내용 (Details)
+- Basic match: `match day: case 1: print("Monday") ... case 7: print("Sunday")`. [S1]
+- Default case: `match day: case 6: ... case 7: ... case _: print("Looking forward to the Weekend")`. [S1]
+- Combined values: `case 1 | 2 | 3 | 4 | 5: print("Today is a weekday")`. [S1]
+- Guarded case: `case 1 | 2 | 3 | 4 | 5 if month == 4: print("A weekday in April")`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 요일/상태 판별처럼 elif 체인이 길어질 상황에서 대안으로 쓰인다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Combined values with a default case (Python):
+```python
+match day:
+    case 1 | 2 | 3 | 4 | 5:
+        print("Today is a weekday")
+    case 6 | 7:
+        print("I love weekends!")
+    case _:
+        print("Unknown day")
+```

+## ✅ 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 Elif]], [[Python If Statement]]
+- **참조 맥락:** elif 체인이 길어질 때의 대안 — 다른 언어의 switch 문에 대응.
