# [[Python Statements]]

## 🎯 한 줄 통찰 (One-line insight)
A Python statement normally ends at the line break, not a semicolon — semicolons are legal but rarely used, and omitting any separator between two statements on one line is a syntax error. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Statement** — a programming instruction to be executed; in Python it usually ends when the line ends. [S1]
- **No semicolon required** — unlike Java or C, Python statements don't need a trailing `;`. [S1]
- **Sequential execution** — multiple statements execute one by one in the order written. [S1]
- **Semicolons are optional** — can separate multiple statements on one line with `;`, but this is rarely used since it hurts readability. [S1]
- **Missing separator is an error** — two statements on the same line without a newline or `;` raises `SyntaxError: invalid syntax`. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Best practice: one statement per line** — the source explicitly recommends this for readability, even though semicolon-chaining is legal. [S1]

## 📖 세부 내용 (Details)
- Basic statement: `print("Python is fun!")`. [S1]
- Multiple statements via semicolon (legal but discouraged): `print("Hello"); print("How are you?"); print("Bye bye!")`. [S1]
- Missing separator (invalid): `print("Python is fun!") print("Really!")` → `SyntaxError: invalid syntax`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 이후 모든 코드 예제에서 한 줄에 한 문장이라는 관례가 일관되게 적용된다. [S1]

## 💻 코드 패턴 (Code patterns)
Sequential statements (Python):
```python
print("Hello World!")
print("Have a good day.")
print("Learning Python is fun!")
```
