Write a python program that reads from a text file whose name is provided by the user, a list of a coffee shop products ordered by a customer (a sample input file is shown below). Each line contains item name, quantity and price (in biza) per product. Compute and display the total payment amount (in riyals) for each product as well as the total bill. Your program should consider the following erroneous cases: • The file does not open/exist The format of the data in the file is incorrect (e.g. quantity = "!" or price "8&0"), in which case RuntimeError exception should be raised and the processing stops. Note: Make sure you close any open file even if an error occurs.
