Question

1. Write a program named filemaker.py that will be used to store the first name and age of some friends in a text file named friends.txt. The program must use a while loop that prompts the user to enter the first name and age of each friend. Each of these entries should be written to its own line in the text file (2 lines of data per friend). The while loop should repeat until the user presses Enter (Return on a Mac) for the name. Then, the file should be closed and a message should be displayed. See Sample Output.

SAMPLE OUTPUT

Enter first name of friend or Enter to quit Denny

Enter age (integer) of this friend 24

Enter first name of friend or Enter to quit Penny

Enter age (integer) of this friend 28

Enter first name of friend or Enter to quit Lenny

Enter age (integer) of this friend 20

Enter first name of friend or Enter to quit Jenny

Enter age (integer) of this friend 24

Enter first name of friend or Enter to quit

File was created

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
