Question 4 of 8intermediate🔧 ApplyShort Answer2 marks

Use assert statement in Question No. 3 to test the division expression in the program.

Correct Answer

The assert statement can be used to test the division expression by verifying that the denominator is not zero before performing division. The syntax is assert Expression[,arguments] where if the expression evaluates to false, an AssertionError is raised.

The modified code is: python numerator = int(input("Enter numerator: ")) denominator = int(input("Enter denominator: ")) assert denominator != 0, "Denominator cannot be zero" quotient = numerator / denominator print("Quotient is:", quotient)

In this code, the assert statement evaluates the condition denominator != 0. If the user enters zero as the denominator, the expression becomes false, and an AssertionError is raised with the message "Denominator cannot be zero". This prevents the division operation from executing with an invalid denominator value, thus testing the division expression.

Explanation

The question requires students to modify the code from Question 3 (which accepted two numbers and displayed quotient) to use an assert statement instead of raise. The textbook demonstrates that assert evaluates an expression and raises AssertionError if false. Students should apply this to check the denominator before division, similar to how Program 1-1 uses assert to check for negative numbers.

Solution Steps

  1. Step 1: Accept two numbers from user (numerator and denominator)

  2. Step 2: Write assert statement with condition denominator != 0 and error message

  3. Step 3: If denominator is 0, AssertionError is raised with custom message

  4. Step 4: If condition is true, perform division and display quotient
