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 Cutput.

Write a python program that includes pseudocode. Must use basic python programming methods. 

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  
   ```

**Exercise 2: File Handling and Average Calculation**

In this task, you are required to write a Python program named `filereader.py`. This program will read and display data from a file called `friends.txt`. Additionally, the program should determine and print the average age of the friends listed in the file. 

### Steps to Complete:

1. Use an **accumulator** to sum the ages.
2. Use a **counter** to keep track of the number of entries.
3. Implement a **while loop** to process the file, print the data, and update the accumulator and counter.
4. Close the file after processing.
5. Display the average age of the friends, rounded to one decimal place.

### 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
```
