# [[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)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 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):
```python
s = "café"
b = s.encode("utf-8")
print(b.decode("utf-8"))  # café
```

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

## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[Python Tutorial]]
- **관련 개념:** [[Python Bytearray]], [[Python Memoryview]], [[Python Data Types]]
- **참조 맥락:** 이진 데이터를 다뤄야 할 때 사용 — 불변이 필요하면 bytes, 가변이 필요하면 bytearray.
