7.13 Inheritance

Starting from one class, we can derive other classes that inherit and modify the original’s behavior and functionality. Inheritance allows us to specialize instances while reusing code from the class hierarchy.

In section 1.10, we focused on Bay leaves, but here we return to guitars and their various types. Let’s begin with a basic definition of the Guitar class. The full and documented code that we develop here is in Appendix D.

class Guitar:
    def __init__(self, brand, model, year_built, strings=6):
        self._brand = brand
        self._model = model
        self._year_built = year_built
        self._strings = strings

    def __str__(self):
        return f"{self._strings}-string " \
            + f"{self._year_built} " \
            + f"{self._brand} {self._model}"

print(Guitar("Fender", "Stratocaster", "2012"))
