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):

cars = ["Ford", "Volvo", "BMW"]
cars.append("Honda")
cars.pop(1)
