docs(10_Wiki): 위키 구조 정리 — 언어 튜토리얼 카테고리 폴더 제거 + 신규 자산 동기화

Topic_CSS/Topic_HTML/Topic_JavaScript/Topic_Prompt/Topic_Comfyui 등 기존 카테고리 폴더를 정리하고, Topic_Graphic/Dev 등 신규 산출물과 Topics 내부 세션/메모리 기록을 동기화.

+# [[Python Range]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+range() is its own immutable sequence type (not directly printable as a list of numbers) that supports slicing, membership testing, and len() — but must be wrapped in list() to actually see its contents. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`range()`** — returns an immutable sequence of numbers; commonly used for loop counts. [S1]
+- **1-argument form** — `range(stop)`; start defaults to 0, stop is exclusive. [S1]
+- **2-argument form** — `range(start, stop)`. [S1]
+- **3-argument form** — `range(start, stop, step)`; step defaults to 1. [S1]
+- **Not directly displayable** — a range object must be converted via `list()` to see its numbers. [S1]
+- **Slicing** — `r[2]` gets a single value; `r[:3]` returns a new range object (not a list). [S1]
+- **Membership test** — `in` works on ranges. [S1]
+- **`len()`** — supported directly on a range. [S1]
+
+## 📖 세부 내용 (Details)
+- One argument: `x = range(10)` → 0 to 9. [S1]
+- Two arguments: `x = range(3, 10)` → 3 to 9. [S1]
+- Three arguments (step): `x = range(3, 10, 2)`. [S1]
+- Convert to list: `print(list(range(5)))`. [S1]
+- Slicing: `r = range(10); print(r[2]); print(r[:3])` — the second print returns a range object. [S1]
+- Membership: `r = range(0, 10, 2); print(6 in r); print(7 in r)`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — Python For Loops 챕터에서 이미 range()의 반복 용도가 다뤄졌고, 여기서 슬라이싱/멤버십/길이 등 시퀀스 연산으로 확장된다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Slicing a range returns another range, not a list (Python):
+```python
+r = range(10)
+print(r[2])   # 2 (single value)
+print(r[:3])  # range(0, 3) (a new range object)
+```
+
+## ✅ 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 Lists]]
+- **참조 맥락:** 반복 횟수 지정의 기본 도구 — 슬라이싱/멤버십 등 시퀀스 공통 연산도 지원.
