"""
This program prompts the user to enter rainfall amounts (in inches) for 12 months of one year. The values are stored into a list.
Using the list created, the program will print out:
• The total rainfall
• The average monthly rainfall (Rounded to two decimal places.)
• The month with the most rain
• The month with the least rain
If the user enters a negative number for a month, user is prompted to re-enter a non-negative value for the month.
