Python Bytearray

🎯 한 줄 통찰 (One-line insight)

bytearray is the mutable counterpart to bytes — same integer-0-255 sequence semantics, but individual elements can be reassigned in place. [S1]

🧠 핵심 개념 (Core concepts)

• bytearray — a mutable sequence of integers in range 0-255, useful when a modifiable byte sequence is needed. [S1]
• Creation — from a size (bytearray(5)), from an iterable of integers, or by decoding bytes. [S1]
• Mutability — individual items can be changed by index assignment. [S1]
• Common operations — indexing, slicing, appending, extending, .find(), .replace(); convertible to bytes(). [S1]

🧩 추출된 패턴 (Extracted patterns)

• In-place item mutation — b[0] = 97 changes a single byte value directly, something plain bytes cannot do. [S1]

📖 세부 내용 (Details)

• Create from size: x = bytearray(5). [S1]
• Create from values and mutate: b = bytearray([65, 66, 67]); b[0] = 97; print(b) # bytearray(b'aBC'). [S1]
• Append and decode: b = bytearray(b"Hello "); b.extend(b"World"); print(b.decode("utf-8")). [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — bytes의 가변(mutable) 대응물로, 바이트 단위 수정이 필요할 때 사용된다. [S1]

💻 코드 패턴 (Code patterns)

Mutate a single byte in place (Python):

b = bytearray([65, 66, 67])
b[0] = 97  # change 'A' to 'a'
print(b)   # bytearray(b'aBC')

• 상태: draft
• 검증 단계: conceptual
• 출처 신뢰도: B (W3Schools — widely used educational reference, not a primary standards body)
• 신뢰 점수: 0.87
• 중복 검사 결과: 신규 생성 (New discovery)

🔗 지식 그래프 (Knowledge Graph)

• 상위/루트: Python Tutorial
• 관련 개념: Python Bytes, Python Memoryview
• 참조 맥락: 바이트를 직접 수정해야 할 때 사용 — 불변이면 충분하면 bytes를 대신 사용.
