# Week 4 Ex 7: This program calculates total and monthly average rainfall for selected years
# Written by Greg Lamb.

#User enters number of years worth of data - first variable for loop 1
years = int(raw_input("Enter the number of years worth of data you need: "))
print ("\nI'm looking for {} years worth of data: ".format(years))
#print years

for year in range(1, years+1): #loop 1 itera
    #print(year)

#Declare aditional variables for loop 2
    rainfallTotal = 0
    numMonths = 12
    
    #loop 2 iterates 12 times and keeps a running total of monthly rainfall entered by user
    for month in range(1,numMonths+1):  
        rainfallInches = float(raw_input("How many inches of rainfall for month number {}: ".format(month)))
        rainfallTotal = rainfallTotal + rainfallInches
        print("Month {} had {} inches of rain. Total rainfall in inches so far is {} ".format(month,rainfallInches,rainfallTotal))

#The program design criteria ask for the total number of months for the period as well as
#the total number of rainfall inches and monthly average rainfall for the period.  totalMonths 
#and aveRainfall are the remaining variables calculated at the back end of loop 1

totalMonths = years * month
#print totalMonths

aveRainfall = rainfallTotal / totalMonths
#print aveRainfall

#Output in next line satisfies the program's design criteria
print("Total rainfall for the period is {} inches and the total number of months worth of data is {}, \nwhich results in a monthly average for the period of {} inches.".format(rainfallTotal,totalMonths,aveRainfall))
