Defining Classes

Built-in classes and classes imported from Python packages are sometimes sufficient for our requirements. However, often you want to invent a new type of object because there isn't an object in the standard libraries that has the properties/methods that you require. Recall that a class is like a template for creating a new object.

For example, create a new class called Australian:

>>> class Australian():
    is_human = True
    enjoys_sport = True 

You now have a new template for creating Australian objects (or people, if you prefer). Our code assumes that all new Australians will be human and enjoy sport.

You will firstly create a new Australian:

>>> john = Australian()

Check the class of our Australian:

>>> type(john)
<class '__main__.Australian'>

You will also view some of John's attributes:

>>> john.is_human
True
>>> john...
