Question

Q: Design a program that lets the user enter the total rainfall for each of 12 months into an array. The program should calculate and display the total rainfall for the year, the average monthly rainfall, and the months with the highest and lowest amounts.

Create parallel arrays for the month names and rainfall amounts for each month. Use month names (i.e. January, February, March, etc.) when printing out the months with the highest and lowest amounts. Include a modular (no global variables or constants) approach that includes and uses (at least) a main module and the following functions:
• GetLargestRainfall  takes parameters of the array of rainfall statistics and the size of the array. Returns the index of the array element with the largest rainfall
• GetSmallestRainfall  takes parameters of the array of rainfall statistics and the size of the array. Returns the index of the array element with the smallest rainfall

1- create IPO chart for GetLargestRainfall funcation and GetSmallestRainfall function.

2- create the properly aligned textbook fromat pseudocode.

3- Create the python source code, that represent the pseudocode requirements.

Note: Please answer all the question.

Note: single question with different parts, it just all the information.

Code Snippet:

def GetSmallestRainfall(arr,n):
   lowest = arr[0]
   lowestIndex = -1
   for i in range(n):
       if arr[i] <= lowest: #Calculating lowest rainfall index
           lowest = arr[i]
           lowestIndex = i
   return lowestIndex

def GetLargestRainfall(arr,n):
   highest = arr[0]
   highestIndex = -1
   for i in range(n): #Calculating highest rainfall index
       if arr[i] >= highest:
           highest = arr[i]
           highestIndex = i
   return highestIndex

def totalRainfall(arr,n):
   total = 0
   for i in range(n):
       total += arr[i] #Calculating total

   return total

def averageMonthlyRainfall(arr,n):
   average = totalRainfall(arr,n)/n #average
   return average

if __name__ == '__main__':
   #Months List
   months = ['January', 'February', 'March', 'April', 'May', 'June', 'July','August', 'September', 'October', 'November', 'December']
   arr = []
   for i in range(12): #Iterating over 12 as there are 12 months
       arr.append(float(input('Enter the Rainfall for %s: ' %months[i])))
   n = len(arr) #Length of the array
   print("Total rainfall : %d" %(totalRainfall(arr,n))) #Calling functions
   print("Average Monthly Rainfall %.2f" %(averageMonthlyRainfall(arr,n)))
   index = GetLargestRainfall(arr,n)
   print("Largest Rainfall %s %.2f" %(months[index],arr[index]))
   index = GetSmallestRainfall(arr,n)
   print("Smallest Rainfall %s %.2f" %(months[index],arr[index]))

Output:

IPO Chart:

Input	Processing	Output
Monthly Rainfall for 12 months in an year.	Compute the Total Rainfall by adding all the monthly rainfalls. Compute the Average Rainfall by calling the Total Rainfall function and dividing the returned value by the length of the array. Compute the Maximum Rainfall by finding the maximum value of the array. Compute the Minimum Rainfall by finding the minimum value of the array.	Total Rainfall across all the months. Average Monthly Rainfall. Maximum Rainfall of the 12 months stats. Minimum Rainfall of the 12 months stats.
