- Slide Type Slide • Exercise # 4 A hotel salesperson enters sales in a text file. Each line contains the following, separated by semicolons: • The name of the client, the service sold (such as Dinner, Conference, Lodging, and so on), • The amount of the sale, and the date of that event. • Write a program that reads such a file and displays the total amount for each service category. Display an error if the file does not exit or the format of the record is incorrect. No need to display anything else in this regard. Note that you can assume that the dates are entered correctly (no need to validate them). You may also assume that the name of the input text file is inputex4.txt. • Make sure you use a dictionary in your solution. • Sample run is included below for the given input file inputex4.txt Summary of total sales according to services Dinner 634.75 Conference 1133.25 Lodging Dinner and Lodging 550.25 625.14 Slide Tyne Fragment varrow_forwardBulk File Rename Application Create an application which renames files in bulk.

The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it.
