Implementation

Let's look at a relatively simple application to illustrate adaptation: a club's activities, mainly the need to organize performances and events for the entertainment of its clients, by hiring talented artists.

At the core, we have a Club class that represents the club where hired artists perform some evenings. The organize_performance() method is the main action that the club can perform. The code is as follows:

class Club: 
    def __init__(self, name): 
        self.name = name

Most of the time, our club hires a DJ to perform, but our application addresses the need to organize a diversity of performances, by a musician or music band, by a dancer, a one-man or one-woman show, and so on.

 

Via our research to try and reuse existing code, we find an open source contributed library that brings us two interesting classes: Musician...
