With while-loops we can now write some super complex programs – once that we way more sophisticated than what we have done before. In this video we show how to create a complete dice game with…

In this video we show one of the most powerful while-loop techniques: computing to convergence. Convergence is a concept that most students learn in Calculus, and so we will use a little Calculus in…

Types guarantee that an object supports a set of operations (methods) and has a certain set of attributes. However, in this video we show that we can actually get this information without typing an…

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…

In this video we motivate the conept of subclasses by looking at a potential application. As software becomes more and more complex, we have to leverage features that allow us to work with other,…

Dictionaries are mutable. In this video we show how to alter there contents. This includes reassigning the value of a dictionary for a given key. But it also includes adding and deleting keys.

Lists require that we explicitly show the folder when visualize them. In this video we show what that means when a list contains other objects that have their own folders. The result is a chain of…

Try-except statements will allow use to write functions that we could not write with conditional statements. In this video, we show how to use try-except as a general programming tool.

In this video we intrduce a new control structure: the try-except statement. As we will see, it looks very similar to an if-else statment with some important differences.

We now know how to do assert statements to create errors. But the error messages are a little cryptic. In this video we talk about how we can do a better job.
