Sorting algorithms can be quite sophisticated. In order to understand them, we need some way to visualize them. In this video, we introduce horizontal notation, which is a way to track how much of a…

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…

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…

The primary role of an object is to store attribute variables. In this video we demonstrate the easiest way to add attributes to an object. We see that we can also add attributes to class folders as…

Dictionaries are not sliceable, but they are iterable. In this video we show the many different ways you can use a dictionary in a for-loop. The primary thing to understand is that you have to…

Strings, lists, and tuples are not the only iterable types. In this video we introduce the range function, which creates another iterable value. This is going to allow us to do several things that we…

In this video we introduce a new control-structure: the for-loop. This control structure is specifically designed for processing iterable types like strings, tuples, and lists.

The big advantage that lists have over tuples is that they are mutable.In this video we show how to write assignment statements that modify the contents of a list.

In this session we use the Python visualizer to help us better understand objects, a new type of data. For many students this is the first big difficulty jump in this course.This class is going to…

We know what happens when we call a function. But as we show in this video, Python also does something very important when we define a function. It has to store the definition somewhere.

When you work on Assignment 3, you will discover that the color objects have some significant restrictions on how they can be used. These restrictions are called attribute invariants, and they are…

Objects are these folders that contain a portfolio of variables. These variables are called attributes. In thie video we talk about how we can access these attributes, or even change them.

In the previous video, we wrote a function definition in the interactive shell. In this video, we write it in a module. We show how this changes things when you call the function.

Working on modules will require a new type of program: the code editor. In this video we discuss why we prefer Atom Editor and how you should use it in this course.
