Create an order file similar to sultan.bxt, and save it as your name.2. Test your code using the provided input files and the one you create, and confirm theoutput. Take screenshots of the output files, input files you made, and your code, putthem all in one pdr document.3. Submit one zipped file containing the following:your code (in ipynb file),your input and output files (in txt files),and the pdf document prepared in step 2.m254 21332 In this project, you will write a Python program that generates a bill for some store. The storeowner provides two text files as an input. The program first reads the input file named"items.txt" which contains a list of all items in the store with their unit-prices. The programstores the items in in one list called itemList according to their order given in the items.Ixt file.The index of each item in this list is used as a serial number (S/N) of the item. Then the programreads the other input file named "promo.txt" which contains the information about specialdiscounts for promo items. When a customer places an order, a text file is created where eachlines has the item S/N and the quantity. The program then generates a bill for the customer usingthe information stored in the itemList.Input File Format:1. Input file (items.txt): each line in this file contains the item name followed by its price.2. Input file (promo.txt): a list of item S/N for all items on promo.3. Order file: each line in this file contains the item S/N followed by the quantity.Samples of these input files are given below. (See File Samples).Main Requirements:1. When it is started, the program reads the items.Ixt file, and stores the data in one listnamed itemlist. Each entry in this list has three parts: itemName, itemPrice, anditemType. Both the name and the price are given in the items.txt file. The itemType iseither S for standard items (by default) or P for promo items (updated next in Step 2).2.The program then reads the promo.txt files, and for each item S/N in the file, it updatesthe type of that item in the list to (P).3. The program then prompts the user to enter the order file name.• Please enter the order file name (or Q to quit):• When the user types the order file name, the program processes the order togenerate the bill.program will keep prompting for new orders and generating bills until theuser hit Q to quit.4. The program should compute the amount of each item in the order according to its unitprice and quantity. Then it adds up all the amounts and finds the total. It applies discountsif any. Then, it adds the 15% VAT and find the grand total.5. There are two kinds of discount in this store.• For Promo items, apply BOGO (buy-one-get-one free).• If the total amount (excluding VAT and promo items) is more than SAR 1000, thestore will give one of the purchased items for free. So, the program should deductthe price of one unit of the most expensive item included in the order.All discounted amounts are added up, and only the total of the discount will beshown in the bill and deducted from the grand total before applying the VAT.6. The program then creates the bill and saves it in output file. The output file name isbill_XXXX where xXXx is the name of order file. An example of the bill output file is givenin File Samples below.Technical Requirements:1. You should use functions to perform common tasks. For example, to read and process aline from an input file, to write a line to an output file, to perform common computations,--- ete.2. The program should be well-documented.3. The output format should be similar to the ones given in the sample files.Sample Files: (you can copy/paste and save below data as text file for input)1. items.txIApples10.50BananasCherries12.2525.0010.00DonutsEggsFlowers2.5015.00GrapesHP_InkIcecream20.00150.0050.00JavacoffeeZafron250.00350.002. promo.txt (Donuts and Flowers are on promo this month)3. sultan.txt (input file for sultan's order)13.52.045.042193010112

After the reading is done, the file should be closed. If the file is not available, the program should be closed immediately. You should mention "System call" beside each instruction which are supposed to use a system call function. *
