Python 14.5 : Exercise : add age

Python is a popular programming language that is used by developers for a wide range of applications. One of the most important aspects of programming is the ability to add new features to an existing program, and the "Exercise: add age" is a great example of how this can be done in Python.

The exercise involves adding a new feature to an existing program that calculates the average age of a group of people. The new feature involves asking the user to input the age of each person in the group, and then adding up all the ages to calculate the average.

To accomplish this, the developer must first create a new function that will prompt the user to input the age of each person in the group. Then, the developer must modify the existing function that calculates the average age to include the new input values.

This exercise is a great way for developers to practice their Python skills and learn how to add new features to existing programs. It also demonstrates the importance of modularity in programming, as each function can be modified independently of the others without affecting the overall program.

Overall, the "Exercise: add age" is a valuable learning experience for anyone looking to improve their Python programming skills and gain a better understanding of how to add new features to existing programs.
