# [[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 declaration** — `x = 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]
|
|
```python
|
|
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):
|
|
```python
|
|
if 5 > 2:
|
|
print("Five is greater than two!")
|
|
```
