Item list We have a list of products and their prices. Each line contains the name of the item and its price separated by a comma. Write a program that reads a txt file and computes the following:
The number of lines in the file
The most expensive product
The least expensive product
Edge cases:
If multiple items qualify as the most/least expensive product, then print only the first product.
The files have not been pre-processed. It might contain empty lines in the file.
If the file cannot be opened, then print "Could not open file."
Sample file(products. txt): Apple EarPods, 19.99
Bose QuietComfort 35, 292.42
Apple AirPods , 139.00
Beats Solo3, 189.98
