2. Now write a program named filereader. py that reads and displays the data in friends. txt. This program should also determine and print the average age of the friends on file. That will require an accumulator and a counter. Use a while loop to process the file, print the data, and modify the accumulator and counter. Then close the file and display the average age accurate to one decimal place. See the Sample Output.. SAMPLE OUTPUT My friend Denny is 24 My friend Penny is 28 My friend Lenny is 20 My friend Jenny is 24 Average age of friends is 24.0

see explaination

Explanation:

# python code filereader.py

import sys

import readline

from sys import stdin

import random

## Open the file with read only permit

f = open('inputfile.txt')

## Read the first line

sum = 0.0

count = 0

#read file till the file is empty

while True:

line = f.readline()

if ("" == line):

print "Average age of friends is", sum/count

break

list = line.split()

print "My friend ",list[0], " is", list[1]

sum = sum + int(list[1])

count = count + 1

f.close()

'''

inputfile.txt

Denny 24

Penny 28

Lenny 20

Jenny 24

output:

My friend Denny is 24

My friend Penny is 28

My friend Lenny is 20

My friend Jenny is 24

Average age of friends is 24.0
