Chapter 5. When to Use Object-oriented Programming
In previous chapters, we've covered many of the defining features of object-oriented programming. We now know the principles and paradigms of object-oriented design, and we've covered the syntax of object-oriented programming in Python.
Yet, we don't know exactly how and when to utilize these principles and syntax in practice. In this chapter, we'll discuss some useful applications of the knowledge we've gained, picking up some new topics along the way:
- How to recognize objects
- Data and behaviors, once again
- Wrapping data in behavior using properties
- Restricting data using behavior
- The Don't Repeat Yourself principle
- Recognizing repeated code
Treat objects as objects
This may seem obvious; you should generally give separate objects in your problem domain a special class in your code. We've seen examples of this in the case studies in previous chapters; first, we identify objects in the problem and then...
