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):

print(6 & 3)  # 2 (0110 & 0011 = 0010)
print(6 | 3)  # 7 (0110 | 0011 = 0111)
print(6 ^ 3)  # 5 (0110 ^ 0011 = 0101)
