Question

Post a Python program with a scenario that accepts at least three values as input, performs some computation and displays at least two values as the result. The program must include an if statement that performs different computations based on the value of one of the inputs. Include comments in your program that describe what the program does. Also post a screen shot of executing your program on at least two test cases.

Answer 1

The program can be designed as follows:

• Create a function with three parameters- sign, num1 and num2.
• If the sign is positive, calculate sum and product.
• Otherwise multiply the sum and product by -1.
• Return the product and the sum
• Call the function with two different set of values.

The python program:

#function that will return the sum and product of two numbers
#the parameters are a sign and two numbers
def func(sign,num1,num2):
    
    #sign is positive
    if sign > 0:
        ans = num1 * num2
        sum1 = num1 + num2
        
    #sign is negative
    else:
        ans = num1 * num2 * -1
        sum1 = (num1 + num2) * -1
        
    return ans,sum1
    
#calling func with negative sign and two numbers
product,addition = func(-1,3,4)

print("Product: %i" %product)
print("Addition: %i" %addition)

#calling func with positive sign and two numbers
product2,addition2 = func(1,4,6)

print("\nProduct2: %i" %product2)
print("Addition2: %i" %addition2)
