Input a list of positive numbers, find the mean (average) of the numbers, and output the result. Use a subprogram to input the numbers, a function to find the mean, and a subprogram to output the result. Use a subprogram to Input the numbers, a Function to find the mean and a subprogram to output the Result.

def inputNumber():

   l = []

   num = int(input("Enter the number of integers you want to enter\n"))

   for i in range(0,num):

       print("Enter the ", i+1, " integers ")

       a = float(input())

       l.append(a)

   return l

def averageCalculator(l):

   total = 0

   for i in l:

       total += i

   avg = total/len(l)

   return avg

def printoutput(avg):

   print("The average of numbers is ", avg)

l = inputNumber()

avg = averageCalculator(l)

printoutput(avg)

Explanation:

A subprogram may be considered as a method where we pass some values in the arguments and return some value.

The answer is written in python language, where we have used

inputNumber() subprogram to get the input from the user.

function averageCalculator() to calculate the average.

printoutput() subprogram to print the output or the average of the numbers.

Please refer to the attached image for better understanding of the indentation of code.

Now, let us learn about them one by one:

inputNumber(): We get the number of values to be entered as an integer value and then get the numbers as float.

Store the values in a list and return the list to the caller main program.

averageCalculator(l): Contains a list as argument as we got from inputNumber(). It sums all the numbers and divides with total number to find the average. Returns the average value to the caller main program.

printoutput(avg): Contains an argument which is the average calculated in the averageCalculator(). It prints the argument passed to it.
