python A pet shop wants to give a discount to its clients if they buy one or more pets. The discount is equal to 20 percent of the cost of the other items, but not the pets. Implement a function def discount (prices, isPet, nItems) The function receives information about a particular sale. For the ith item, prices[i] is the price before any discount, and isPet[i] is true if the item is a pet. Write a program that prompts a cashier to enter each price and then a Y for a pet or N for another item. Use a price of - 1 as a sentinel. Save the inputs in a list. Call the function that you implemented, and display the discount.

    The following are the program in the Python Programming Language.

    #define function

    def discount (prices, isPet, nItems):

    # declare and initialize variables to 0

    i = 0

    cost = 0

    pets = 0

    item = 0

    item_Cost = 0

    #set the while loop

    while (i < nItems):

    #check the items of the variable

    if isPet[i]:

    #add and initialize in the cost

    cost + = prices[i]

    #increament in the variable by 1

    pets + = 1

    #otherwise

    else:

    #add and initialize in the item_Cost

    item_Cost + = prices[i]

    #increament in the variable by 1

    item + = 1

    #then increment in the variable by 1

    i + = 1

    #check the pet is greater than equal to 1

    #and item is greater than equal to 5

    if (pets > = 1 and item >=5):

    #then, print the message

    print ("You receive discount")

    #set discount of the items

    discount = 0.2 * item_Cost

    # calculate bill after deducting discount

    bill = cost + item_Cost - discount

    #print the bill

    print ("Final Bill amount is", bill)

    #otherwise

    else:

    #print the message

    print ("You do not receive any discount")

    #calculate bill without deducting discount

    bill = cost + item_Cost

    #print the final bill

    print ("Final Bill amount is", bill)

    #set empty list type variables

    price = []

    pet = []

    #set the infinite loop

    while True:

    #get input from the user

    sprice = int (input ("Enter the price (-1 to quit) : "))

    #check that price is not equal to the - 1

    if (sprice! = - 1):

    #add price in the list

    price. append (sprice)

    #ask for choice from the user

    choice = input ("Is it a pet (Y / N) ? ")

    #check the choice of the user is y or Y

    if (choice = = 'Y' or choice = = 'y'):

    # then, add in the pet

    pet. append (True)

    #otherwise

    else:

    #not add in the pet

    pet. append (False)

    print ("")

    #break the loop

    else:

    break

    #declare variable that store the length

    items = len (price)

    #call and initialize the variable

    discount (price, pet, items)

    Output:

    Enter the price (-1 to quit) : 96

    Is it a pet (Y / N) ? y

    Enter the price (-1 to quit) : 69

    Is it a pet (Y / N) ? n

    Enter the price (-1 to quit) : 41

    Is it a pet (Y / N) ? n

    Enter the price (-1 to quit) : 52

    Is it a pet (Y / N) ? n

    Enter the price (-1 to quit) : 96

    Is it a pet (Y / N) ? n

    Enter the price (-1 to quit) : 74

    Is it a pet (Y / N) ? n

    Enter the price (-1 to quit) : - 1

    You receive discount

    Final Bill amount is 361.6

    Explanation:

    The following are the description of the program.

    Firstly, define the function 'discount () ' and pass the arguments 'prices', 'isPet' and 'nItems' in its parameter. Then, declare and initialize the variables 'i' to 0, 'item_Cost' to 0, item to 0, 'cost' to 0 and 'pets' to 0. Then, set the while loop to add the price of the items and the cost of the pets. Set the if-else conditional statement to check the pet is greater than equal to 1 and the items are greater than equal to 5 then, set the discount and print the bill after deduction. Otherwise, print the bill without deduction. Finally, set two list type variable then, set the infinite while loop that gets input from the user and check that the variable is not equal to - 1 then append the data in the list then again check the user input then append in pet otherwise not append in pet and break the loop. Then, set the variable that stores the length of the price and call the following function by passing arguments in its parameter.
