Python Programming in Context, 3rd Edition

11.9 Summary

In this chapter, we designed and implemented a large, multiclass graphical simulation. First, we considered a description of the problem. We picked out the important subjects (nouns) and began to implement classes, one for each. Then, to design a class, we described those things that instances of a class would need to know about themselves (the instance variables) and those things that instances of a class would need to be able to do (the methods). After creating each class, we implemented a function that established many objects, and we let each object perform methods as defined by the initial rules of the simulation. By using random numbers, we were able to provide a degree of uncertainty so that no two runs of our simulation ...
