Python Operators Precedence
🎯 한 줄 통찰 (One-line insight)
Python evaluates parentheses first, then a fixed hierarchy from exponentiation down through logical OR, and falls back to left-to-right evaluation whenever two operators share the same precedence tier. [S1]
🧠 핵심 개념 (Core concepts)
- Operator precedence — the order in which operations are performed. [S1]
- Parentheses highest — expressions inside
()are always evaluated first. [S1] - Same-precedence tie-break — left-to-right evaluation when precedence is equal. [S1]
- Precedence order (highest → lowest) —
()→**→ unary+x -x ~x→* / // %→+ -→<< >>→&→^→|→ comparisons/identity/membership (== != > >= < <= is is not in not in) →not→and→or. [S1]
📖 세부 내용 (Details)
- Parentheses first:
print((6 + 3) - (6 + 3)). [S1] - Multiplication before addition:
print(100 + 5 * 3) # 115, not 315. [S1] - Left-to-right on equal precedence:
print(5 + 4 - 7 + 3)evaluates strictly left to right. [S1]
