Python 3 - Write a program that accepts a date and precipitation for the day (two separate entries). You may use month, day, year or simply month and day since the program will only be calculating max/total/average based on month and not year. The program should continue to ask for user input until the user indicates there are no more entries (loop and sentinel). Write this data to a file. Allow the user to write more data to the file later without overwriting the original data.
