# [[Python Operators Bitwise]]

## 🎯 한 줄 통찰 (One-line insight)
Bitwise operators (`&`, `|`, `^`, `~`, `<<`, `>>`) compare numbers at their binary-digit level rather than as whole values — e.g. `6 & 3` compares `0110` and `0011` bit-by-bit to get `0010` (2). [S1]

## 🧠 핵심 개념 (Core concepts)
- **`&` (AND)** — sets each bit to 1 if both bits are 1. [S1]
- **`|` (OR)** — sets each bit to 1 if at least one bit is 1. [S1]
- **`^` (XOR)** — sets each bit to 1 if exactly one of the two bits is 1. [S1]
- **`~` (NOT)** — inverts all bits. [S1]
- **`<<` (zero fill left shift)** — shifts left, pushing zeros in from the right. [S1]
- **`>>` (signed right shift)** — shifts right, pushing copies of the leftmost bit in from the left. [S1]

## 📖 세부 내용 (Details)
- AND: `print(6 & 3)` → `0110 & 0011 = 0010` = 2. [S1]
- OR: `print(6 | 3)` → `0110 | 0011 = 0111` = 7. [S1]
- XOR: `print(6 ^ 3)` → `0110 ^ 0011 = 0101` = 5. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 플래그 비트 조합, 저수준 최적화 등에서 쓰이는 연산이다. [S1]

## 💻 코드 패턴 (Code patterns)
Bitwise AND/OR/XOR (Python):
```python
print(6 & 3)  # 2 (0110 & 0011 = 0010)
print(6 | 3)  # 7 (0110 | 0011 = 0111)
print(6 ^ 3)  # 5 (0110 ^ 0011 = 0101)
```
