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 Sets]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+A set is Python's unordered, unindexed, no-duplicates collection — and its duplicate detection treats True/1 as the same value, and False/0 as the same value, since equality (not just type) determines duplication. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Set** — one of Python's 4 built-in collection types; unordered, "unchangeable"* (items can't be modified, but can be added/removed), unindexed, written with `{}`. [S1]
+- **Unordered** — items have no defined order and cannot be accessed by index or key. [S1]
+- **No duplicates** — sets silently drop duplicate values on creation. [S1]
+- **`True`/`1` and `False`/`0` collapse** — these pairs are treated as the same value for duplicate purposes. [S1]
+- **`set()` constructor** — alternative creation syntax. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Value-equality-based dedup, not type-based** — `{True, 1, 2}` collapses to `{True, 2}` (or `{1, 2}`) because `True == 1` in Python, illustrating that set uniqueness follows `==`, not `type()`. [S1]
+
+## 📖 세부 내용 (Details)
+- Basic creation: `thisset = {"apple", "banana", "cherry"}`. [S1]
+- Duplicate dropped: `thisset = {"apple", "banana", "cherry", "apple"}` → duplicate "apple" ignored. [S1]
+- True/1 collapse: `thisset = {"apple", "banana", "cherry", True, 1, 2}`. [S1]
+- Constructor: `thisset = set(("apple", "banana", "cherry"))`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음. "unchangeable"이라는 표현 자체가 각주(*)로 "제거·추가는 가능하다"고 완화됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — Set 연산(union/intersection/difference)은 이후 Join Sets 챕터에서 본격적으로 다뤄진다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+True/1 duplicate collapse (Python):
+```python
+thisset = {"apple", "banana", "cherry", True, 1, 2}
+print(thisset)  # True and 1 collapse to one value
+```

+## ✅ 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 Lists]], [[Python Frozenset]], [[Python Sets Join]]
+- **참조 맥락:** 4대 컬렉션 타입 중 하나 — 고유값 집합 연산이 필요할 때 사용.
