Question

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for the inches of rainfall for that month. After all iterations, the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period. Input Validation: Do not accept a number less than 1 for the number of years. Do not accept negative numbers for the monthly rainfall.

Answer 1

Answer:

#variable initialization

m = 0

Sum = 0

#accept number of years

Y = int(input("Enter number of years: "))

#validated the years are in the range 1 to 10 or not

while Y < 1 or Y > 10:

   Y = int(input("Enter number of years: "))

   #if year are not in the range continue loop

   if Y < 1 or Y > 10:

       print("Invalid years..!!!")

#loop for number of years

for i in range(Y):

   #print year

   print("Enter Rainfall in year", i+1," : ")

   #loop for 12 times

   for i in range(12):

       #enter rainfall for every month

       print("Enter Rainfall in month", i+1, ": ", end =' ')

       V = float(input())

#calculate total rain fall

       Sum = Sum + V

      #calculate total month

       m = m + 1

#calculate average rainfall per month

Avg = Sum/m

#display total rainfall

print("Total rainfall = ", Sum)

#display average rainfall

print("Average rainfall per month = ", Avg)
