A cookie recipe calls for the following ingredients: • 1.5 cups of sugar • 1 cup of butter • 2.75 cups of flour The recipe produ
True [87]

The program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient is corresponds to the ingredients mentioned above.

<h3>Further explanation</h3>

Python is a general-purpose programming language. We want to write a python program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient.

48 cookies = 1.5 cups of sugar + 1 cup of butter + 2.75 cups of flour, so:

def main():

   cookies = float(input("How many cookies would you like to make?\n>"))

   sugar = (1.5 * cookies) / 48.0

   butter = cookies / 48

   flour = (2.75 * cookies) / 48

   print("To make ", cookies, " cookies, you will need:\n", \

         format(sugar, '.2f'), " cups of sugar\n", \

         format(butter, '.2f'), " cups of butter\n", \

         format(flour, '.2f'), " cups of flour", sep='')

   redoQuery()  

def redoQuery():

   yn = input("Would you like to check another batch size? (y/n)\n>")

   if yn == 'y':

       main()

   elif yn =='n':

       exit()

   else:

       print("Please enter only a lowercase \'y\' or lowercase \'n\'," \

             "then press enter")

       redoQuery()

main()

The run program is shown in the attachment below.
