So below is the question of the problem for my class. I have attached a picture of my python program and I keep getting than error message. I have also attached the list of the friends and age. using python 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..
