Python Coding Challenge - Question with Answer (ID 151026)

 

Explanation:

🟢 Step 1: Understand the Operators

This expression uses two logical operators:

- and returns the first falsy value, or the last value if all operands are truthy.

- or returns the first truthy value, or the last value if all operands are falsy.

Important: In Python, and has higher precedence than or, so the and expressions are evaluated first.

🟢 Step 2: Evaluate the First and

5 and 0

- 5 is truthy because it is a non-zero number.

- Since the first operand is truthy, and returns the second operand, 0.

Result:

0

The expression becomes:

print(0 or 7 and 3)

🟢 Step 3: Evaluate the Second and

7 and 3

- 7 is truthy.

- Therefore, and returns the second operand, 3.

Result:

3

The expression becomes:

print(0 or 3)

🟢 Step 4: Evaluate or

0 or 3

- 0 is falsy in Python.

- The or operator therefore returns the second operand, 3.

Result:

3

🟢 Step 5: Display the Final Result

print(5 and 0 or 7 and 3)

Python prints the final value returned by the expression.

✅ Final Output

3
