# [[Python Tuples Unpack]]

## 🎯 한 줄 통찰 (One-line insight)
When variable count doesn't match tuple length, prefixing one variable with `*` collects all the "extra" values into a list — and that starred variable doesn't have to be last; it absorbs exactly as many items as needed to satisfy the other variables. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Packing** — assigning multiple values to a tuple, e.g. `fruits = ("apple", "banana", "cherry")`. [S1]
- **Unpacking** — extracting a tuple's values back into separate variables: `(green, yellow, red) = fruits`. [S1]
- **Count must match** — the number of variables must equal the number of values, unless using `*`. [S1]
- **Asterisk (`*`) collector** — when variables < values, one starred variable name collects the remainder AS A LIST. [S1]
- **Asterisk in the middle** — if `*` is on a variable that isn't last, Python still fills the OTHER variables first/last as needed, giving the starred variable whatever remains. [S1]

## 📖 세부 내용 (Details)
- Basic unpack (counts match): `fruits = ("apple", "banana", "cherry"); (green, yellow, red) = fruits`. [S1]
- Starred unpack, trailing collector: `fruits = ("apple","banana","cherry","strawberry","raspberry"); (green, yellow, *red) = fruits` → `red = ['cherry', 'strawberry', 'raspberry']`. [S1]
- Starred unpack, middle collector: `fruits = ("apple","mango","papaya","pineapple","cherry"); (green, *tropic, red) = fruits` → `green='apple'`, `tropic=['mango','papaya','pineapple']`, `red='cherry'`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — Python Assign Multiple Values 챕터에서 이미 선행 소개된 언패킹 개념이 여기서 별표 문법으로 확장된다. [S1]

## 💻 코드 패턴 (Code patterns)
Starred unpacking in the middle position (Python):
```python
fruits = ("apple", "mango", "papaya", "pineapple", "cherry")
(green, *tropic, red) = fruits
print(green)   # apple
print(tropic)  # ['mango', 'papaya', 'pineapple']
print(red)     # cherry
```

## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** conceptual
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
- **신뢰 점수:** 0.90
- **중복 검사 결과:** 신규 생성 (New discovery)

## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[Python Tutorial]]
- **관련 개념:** [[Python Assign Multiple Values]], [[Python Args Kwargs]], [[Python Tuples]]
- **참조 맥락:** 튜플/리스트 언패킹의 표준 문법 — 함수 가변 인자(`*args`)와 개념적으로 연결된다.
