# [[Python Arrays]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
Python has no dedicated array type — "arrays" in Python are just Lists used array-style, and a real fixed-type array requires importing a library like NumPy. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **No native array type** — Python lists serve the array role; true arrays need a library like NumPy. [S1]
|
|
- **Array (as list)** — holds multiple values under one name, indexed. [S1]
|
|
- **Access/modify by index** — `cars[0]`, `cars[0] = "Toyota"`. [S1]
|
|
- **`len()`** — array length is one more than its highest index. [S1]
|
|
- **Loop with for-in** — same as list iteration. [S1]
|
|
- **`append()`** — adds an element. [S1]
|
|
- **`pop(index)` / `remove(value)`** — remove by index or by value (first occurrence only). [S1]
|
|
|
|
## 🧩 추출된 패턴 (Extracted patterns)
|
|
- **This entire chapter is a list-as-array framing** — every method table row (append/clear/copy/count/extend/index/insert/pop/remove/reverse/sort) is identical to the List Methods chapter — the content doesn't introduce anything new beyond terminology. [S1]
|
|
|
|
## 📖 세부 내용 (Details)
|
|
- Create: `cars = ["Ford", "Volvo", "BMW"]`. [S1]
|
|
- Access: `x = cars[0]`. [S1]
|
|
- Modify: `cars[0] = "Toyota"`. [S1]
|
|
- Length: `x = len(cars)`. [S1]
|
|
- Add: `cars.append("Honda")`. [S1]
|
|
- Remove by index: `cars.pop(1)`. [S1]
|
|
- Remove by value: `cars.remove("Volvo")`. [S1]
|
|
|
|
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
|
소스에서 모순되는 정보는 발견되지 않음. "Python에는 배열이 없다"는 점이 문서 시작과 끝에서 반복 강조됨. [S1]
|
|
|
|
## 🛠️ 적용 사례 (Applied in summary)
|
|
현재 발견된 실제 적용 사례가 없습니다 — 다른 언어에서 넘어온 개발자가 "array"라는 용어로 검색했을 때 List로 안내하는 용어 매핑 문서다. [S1]
|
|
|
|
## 💻 코드 패턴 (Code patterns)
|
|
List used as an array (Python):
|
|
```python
|
|
cars = ["Ford", "Volvo", "BMW"]
|
|
cars.append("Honda")
|
|
cars.pop(1)
|
|
```
|
|
|
|
## ✅ 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 Lists]], [[Python Lists Methods]]
|
|
- **참조 맥락:** 다른 언어의 "array" 개념을 Python List로 매핑하는 용어 안내 문서.
