The functions will take the sales list as an input parameter. Call each function from an if statement in the main method. The yearly function will dynamically calculate the average based on the total of all sales values in the list and the length of the list. Round the results of the monthly average to a maximum of 2 decimal digits. Formatting is not required. The edit function will ask the user for the three-letter month and sales value and make a simple list of these two values. This simple new list will replace the current single month list in the sales list. For the edit function, display an error message if the user doesn't enter a valid three-letter abbreviation for the month. Use the following list as the standard abbreviations. months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
