Antigravity Agent e9cbf23ab5 docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합
이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

Python Variable Names

🎯 한 줄 통찰 (One-line insight)

A legal Python variable name must start with a letter or underscore, contain only alphanumerics/underscores, avoid Python keywords, and is always case-sensitive — with Camel/Pascal/Snake case as the three common multi-word naming conventions. [S1]

🧠 핵심 개념 (Core concepts)

  • Naming rules — must start with a letter or _; cannot start with a number; only alphanumeric characters and underscores allowed; case-sensitive; cannot be a Python keyword. [S1]
  • Legal examplesmyvar, my_var, _my_var, myVar, MYVAR, myvar2. [S1]
  • Illegal examples2myvar (starts with digit), my-var (hyphen), my var (space). [S1]
  • Camel CasemyVariableName (first word lowercase, rest capitalized). [S1]
  • Pascal CaseMyVariableName (every word capitalized). [S1]
  • Snake Casemy_variable_name (words separated by underscores). [S1]

📖 세부 내용 (Details)

  • Legal names: myvar = "John", _my_var = "John", myVar = "John". [S1]
  • Illegal names: 2myvar, my-var, my var. [S1]
  • Three multi-word conventions: Camel/Pascal/Snake case, each solving readability differently. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — Snake Case는 Python 커뮤니티의 사실상 표준 변수/함수 명명 관례로 이후 모든 예제에서 암묵적으로 따라진다. [S1]

💻 코드 패턴 (Code patterns)

Three naming conventions (Python):

myVariableName = "John"   # Camel Case
MyVariableName = "John"   # Pascal Case
my_variable_name = "John" # Snake Case
