Your assignment is to create a python program that uses a graphical user interface (gui) to facilitate grocery store checkoutsfor a fictional store called gerry’s groceries. your program will begin by reading the day’s grocery prices from a csv file called grocerydb. csv. gerry’s groceriessells four different items: milk, orange juice, eggs, and corn flakes. every day, the store owner, gerry, willupdate grocerydb. csvwith the day’s prices. the csv file will always consist of two columns, where the first column contains the name of each item and the second column contains that item’sprice. the prices may change each day, but the store will always sell the same four items. an examplegrocerydb. csvfile is provided alongside the assignment and is also copied below. only treat this file as an example; your code should work with anycsvfile of this format named grocerydb. csv.
