Generators look like normal functions, but they do not behave like them. In this video we show how to visualize them, using the Python Tutor.

We are familiar with iterables, types that we can use in a for-loop. In this video we introduce the iterator. This is a type that can be used in a for-loop, but we can also manually step through the…

When we break up out application in multiple classes, we need to give each class a role. One of the most popular ways to do this is designate a class as a model, a view or a controller. In this video…

Now that we can raise an error of any type, it is time to make our own error types. In this video we show that this is incredibly simple, and needs almost no code.

In this presentation, we continue with several of the classes that we worked on last time. But this time, we create subclasses of them.On the exam, the class question will always be a two-parter. One…

In ths presentation, we will spend the time creating several example classes. This is another major part of the next exam.When we work with classes, it is very important to pay attention to…

As we saw in the previous video, we cannot trust == if we need to test if two variables refer to the same object folder. In this video we show an alternative operator is, which is safe to use because…

Sometimes you do not want to completely override a method. You just want to override part of it, or add a few extra features at the end. In this video, we introduce the super function which allows us…

Subclasses inherit all of the methods of their parent. But suppose you do not want to use the inherited version of a method, but want to define a new one instead? In this video we talk about the…

We have long said that the dot (.) in Python means “inside of the folder”. But which folder? In this video, we show why subclasses makes this question a little less clear. When Python…

Every class must be a subclass of something, and that parent class goes inside of the parentheses. That means that the word object we have been using in all of class definitions is actually a class.…

In this video we show how to define a subclass. It is exactly the same as defining a class, except that now we actually do something with the parentheses in the function header.
