The file contains many lines of grocery items and their cor responding prices. In each line, the format is name of product. price per unit. For example. a line of the file might look like this: 'Pringles,1.48 Note: content like , Pringles, 1·48, is a string, so you will need to convert 1·48 to a floating-point number when calculating the total price. For example, float ('1.48' would return the floating-point 1.48. In practice your code will pass a variable to float) as an argument (not a literal string as shown here). Also, the quotation marks in the above example do not actually exist in the file- they are shown just to remind you that the file contains strings 2. shopping.list: a string that represents a list of things that you want to buy during this shopping trip.

If there is an isemn in the shopping list that does not exist in the file, skip the item and continue processing the rest of the shopping list.
