Explanation:
🟢 Step 1: Understand the Operators
This expression contains three operators:
- // — Floor division
- and — Returns the first falsy operand or the last operand if all are truthy.
- or — Returns the first truthy operand or the last operand if all are falsy.
Important: Arithmetic operations are evaluated before and and or. Also, and has higher precedence than or.
🟢 Step 2: Calculate Floor Division
15 // 4
- Floor division divides two numbers and rounds the result down to the nearest integer.
- \(15 \div 4 = 3.75\)
- Therefore, 15 // 4 returns 3.
The expression becomes:
print(0 or 8 and 3 + 2)
🟢 Step 3: Perform Addition
3 + 2
- Addition is performed before the logical operators.
- The result is 5.
The expression becomes:
print(0 or 8 and 5)
🟢 Step 4: Evaluate and
8 and 5
- The value 8 is truthy.
- Because the first operand is truthy, and returns the second operand, 5.
The expression becomes:
print(0 or 5)
🟢 Step 5: Evaluate or
0 or 5
- The value 0 is falsy in Python.
- The or operator therefore returns the second operand, 5.
✅ Final Output
