def main():

# Local variables

num1 = 0

num2 = 0

# Get the first positive nonzero integer from the

# user.

while num1 <= 0: num1 = int(input(‘Enter the first number: ‘))# Get the second positive nonzero integer from the # user. while num2 <= 0: num2 = int(input(‘Enter the second number: ‘))# Call the multipy function, and display the product. print(num1, ‘times’, num2, ‘is’, multiply(num1, num2))# The multiply function is a recursive function that # accepts two arguments into the parameters x and y, # and returns the value of x times y. # The function assumes that x and y will always hold # positive nonzero integers. def multiply(x, y): if x == 0 or y == 0: return 0 else: return x + multiply(x, y – 1)# Call the main function. main()
