To create the object defined by the class, we use the constructor of the class to instantiate the object. Due to this, an object is also called an instance of a class. The constructor of a class is a special method defined using the keyword __init__ (). The answer, in a few words. In your example, itsProblem is a local variable. Your must use self to set and get instance variables. You can set it in the __init__ method. Then your code would be: def __init__(self): self.itsProblem = "problem". But if you want a true class variable, then use the class name directly: itsProblem = "problem".In this Python Object-Oriented Tutorial, we will be learning about inheritance and how to create subclasses.
