Create a program that allows you to view and edit the sales amounts for each month of the current year.

The program will use a dictionary to store the data instead of a list. Follow the formatting shown in the

sample output

Specifications

Use the text file named monthly$\_$sales.txt that consists of tab delimited rows, where the rows

contain three$-$letter abbreviations for the month and the monthly sales. Create a module level

constant to hold the name of the text file.

The program should contain a function that reads the file and store the sales data for each

month in a dictionary with the month abbreviation as the key for each sales value item. For

each line of text in the file remove the new line character and split the tab delimited row into

a list that is used to create the dictionary elements. This function will return the dictionary

of all key$/$value elements.

The program should contain a function that writes the dictionary values to the file. The

dictionary will be passed to the function as a parameter. For each month and sales amount

key value pair in the dictionary write a tab separated line to the text file.

Whenever the sales data is edited, the program should write the changed data to the text file.

When viewing or editing a month, check if the input month is a valid key in the dictionary and

display a message if the three$-$letter month is not valid.

Use functions to organize the code for each of the commands. monthly$\_$sales.txt
