Chapter 4. Using Modules for Real-World Programming
In this chapter, we are going to use modular programming techniques to implement a useful real-world system. In particular, we will:
- Design and implement a Python package for generating charts
- See how changing requirements can be the downfall of a successful system
- Discover the ways in which modular programming techniques can help you to deal with changing requirements in the best possible way
- Learn that changing requirements can be good, because they give you the opportunity to re-think your program, resulting in more robust and well-designed code
Let's start by looking at the Python chart-generating package we are going to implement, which we will call Charter.
