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 Syntax

🎯 한 줄 통찰 (One-line insight)

Indentation in Python is not cosmetic — it's the mechanism that defines a code block, and inconsistent spacing within the same block is a syntax error, not just a style nit. [S1]

🧠 핵심 개념 (Core concepts)

  • Two execution modes — directly in the command line (>>> print(...)), or as a .py file run via python myfile.py. [S1]
  • Indentation defines blocks — unlike languages where indentation is only for readability, Python requires it to indicate a block of code. [S1]
  • Consistent spacing required — the same block must use the same number of spaces; inconsistent spacing raises an error. [S1]
  • Variables need no declarationx = 5 both declares and assigns in one step (detailed in Python Variables). [S1]
  • Comments start with #. [S1]

🧩 추출된 패턴 (Extracted patterns)

  • Space count is a convention, not a rule — any number of spaces ≥1 is legal, but it must be applied consistently within the same block; four spaces is the most common convention. [S1]

📖 세부 내용 (Details)

  • Correct indentation: [S1]
if 5 > 2:
    print("Five is greater than two!")
  • Missing indentation raises a syntax error. [S1]
  • Inconsistent indentation within one block also raises an error. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 들여쓰기 규칙은 이후 함수/클래스/반복문 등 모든 블록 구조 챕터에서 전제되는 기초 문법이다. [S1]

💻 코드 패턴 (Code patterns)

Indentation defines a block (Python):

if 5 > 2:
    print("Five is greater than two!")
