Pet Food Purchasing Program USE PYTHON
You are tasked with developing a program for a pet food store.
The program keeps track of how many bags of pet food each customer
buys. The store awards a free bag of food to each customer for
every four purchases (in other words, every fifth bag of food is
free). Then the cycle begins again.
Your program should start by reading the food data file,
creating several objects in a list or other structure. It should
then provide the user with a menu of food items (you should come up
with at least 5 different pet food choices).
The program should ask if they are a new customer or a previous
customer, and ask them to type in their name. If it’s a returning
customer, the program should go into the customer file and find how
many bags of food they have previously purchased. The number of
bags purchased should be updated for returning customers. If it’s a
new customer, you’ll be adding a new line to the customer file with
the first purchase.
Your program should be able to list what food is available and
allow the customer to select a food to purchase, showing a price to
the customer, asking for a confirmation, and then outputting the
number of bags of food they have purchased so far. Every fifth bag
of food should be free.
Once a customer has purchased a bag, then the program should
return to the original state, asking for a new customer name.
Required data files and formats:
The pet food data file can be created once and will only be
read. You do not need to update this file programmatically (unless
you want to allow the user to add more products to spice up the
program).
The customer data file will be updated by your program on every
run.
