# [[Python Strings Concatenate]]

## 🎯 한 줄 통찰 (One-line insight)
The `+` operator concatenates strings, but adds no separator automatically — a space or other separator must be inserted explicitly between operands. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`+` operator** — combines (concatenates) two strings. [S1]
- **No automatic spacing** — concatenation is literal; a manual `" "` must be added between words. [S1]

## 📖 세부 내용 (Details)
- Basic concatenation: `a = "Hello"; b = "World"; c = a + b; print(c)  # "HelloWorld"`. [S1]
- With explicit space: `c = a + " " + b  # "Hello World"`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — f-string(String Format 챕터)이 등장하기 전까지의 기본 문자열 결합 방식이다. [S1]

## 💻 코드 패턴 (Code patterns)
Concatenate with an explicit space (Python):
```python
a = "Hello"
b = "World"
c = a + " " + b
print(c)
```

## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** conceptual
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
- **신뢰 점수:** 0.88
- **중복 검사 결과:** 신규 생성 (New discovery)

## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[Python Tutorial]]
- **관련 개념:** [[Python Strings Format]], [[Python Output Variables]]
- **참조 맥락:** f-string 이전의 기본 문자열 결합 방식 — 더 정교한 포매팅은 Strings Format 참조.
