# Last updated April 23, 2015

# Define variables and ask user for the number of years of rainfall they want to average
totalRainfallInches=0
years=input('Enter the number of years of rainfall to be averaged:')
print('The number of years of data to collect is {} years.'.format(years))

# Loop 1 for years
for year in range(1,years+1):
    monthsPerYear=int(12)
    
# Loop 2 for months
    for month in range(1,monthsPerYear+1):
        monthlyRainfallInches=float(raw_input('How many inches of rain fell in month {}:'.format(month)))
        totalRainfallInches=totalRainfallInches + monthlyRainfallInches
   
# Output of total months, total rainfall, and average rainfall per month
totalMonths=years*monthsPerYear
averageRainfall=float(totalRainfallInches/totalMonths)
print('The total rainfall over {} months was {:,.1f} inches and the average rainfall per month was {:,.1f} inch(es).'.format(totalMonths, totalRainfallInches, averageRainfall))
