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 Dictionaries Nested]]
+
+# 참고: 원문 제목은 "Python - Nested Dictionaries"
+
+## 🎯 한 줄 통찰 (One-line insight)
+A dictionary can contain other dictionaries as values, and chained bracket access (`outer["child2"]["name"]`) drills into the nesting exactly like accessing a plain key. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Nested dictionary** — a dictionary whose values are themselves dictionaries. [S1]
+- **Two construction styles** — inline literal nesting, or assembling separate named dicts and combining them into an outer dict. [S1]
+- **Chained access** — `myfamily["child2"]["name"]` accesses the outer dict, then the inner dict. [S1]
+- **Nested loop via items()** — an outer `for x, obj in myfamily.items()` combined with an inner `for y in obj` walks the full nested structure. [S1]
+
+## 📖 세부 내용 (Details)
+- Inline nested literal: [S1]
+```python
+myfamily = {
+    "child1" : {"name" : "Emil", "year" : 2004},
+    "child2" : {"name" : "Tobias", "year" : 2007},
+    "child3" : {"name" : "Linus", "year" : 2011}
+}
+```
+- Assembled from separate dicts: `child1 = {...}; child2 = {...}; child3 = {...}; myfamily = {"child1": child1, "child2": child2, "child3": child3}`. [S1]
+- Chained access: `print(myfamily["child2"]["name"])`. [S1]
+- Nested loop: [S1]
+```python
+for x, obj in myfamily.items():
+    print(x)
+    for y in obj:
+        print(y + ':', obj[y])
+```
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — JSON과 유사한 계층적 데이터 구조를 표현할 때 표준적으로 쓰이는 패턴이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Chained access into a nested dict (Python):
+```python
+myfamily = {
+    "child1": {"name": "Emil", "year": 2004},
+    "child2": {"name": "Tobias", "year": 2007},
+}
+print(myfamily["child2"]["name"])  # Tobias
+```

+## ✅ 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 Dictionaries]], [[Python Dictionaries Loop]], [[Python JSON]]
+- **참조 맥락:** 계층적 데이터 구조 표현의 기본 — JSON 챕터와 자연스럽게 연결된다.
