Python Bytes

🎯 한 줄 통찰 (One-line insight)

bytes is an immutable sequence of integers 0-255 used for binary data, created from literals/encoded strings/integer iterables, and supports the same indexing/slicing/iteration operations as other sequences. [S1]

🧠 핵심 개념 (Core concepts)

• bytes — an immutable sequence of integers in range 0-255, typically for binary data (files, network protocols, UTF-8 text). [S1]
• Creation — from a literal (b"Hello"), by encoding a string (s.encode("utf-8")), or from an iterable of integers. [S1]
• Sequence operations — supports indexing, slicing, iteration, membership tests despite being immutable. [S1]
• Decoding — bytes.decode() converts bytes back to a string. [S1]

📖 세부 내용 (Details)

• Literal creation: x = b"Hello"; print(type(x)). [S1]
• Encoding a string: s = "café"; b = s.encode("utf-8"); print(b) # b'caf\xc3\xa9'. [S1]
• Indexing/slicing/iterating: b = b"ABCDEF"; print(b[0]) # 65; print(b[1:4]) # b'BCD'. [S1]
• Decoding: b = b"caf\xc3\xa9"; print(b.decode("utf-8")) # café. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 가변 버전인 bytearray와 대비해서 이해해야 한다. [S1]

💻 코드 패턴 (Code patterns)

Encode and decode (Python):

s = "café"
b = s.encode("utf-8")
print(b.decode("utf-8"))  # café
