Since dictionaries are mutable, we must represent them with folders. In this video we show what these folders must look like. In doing so, we see that they look suspiciously similar to other folders…

In this video we show how to take recursive definitions from mathematics and implement them in Python. To do this, we will need to have a function call itself in its own definition.

In this session we take a closer look at the three memory areas of Python. This will help us understand what the Python Tutor is showing when we write more complex programs in the future.The…

Lists have many of the same methods as tuples. But since they are mutable, they have even more. In this video we show off some of the mutable methods of lists, which are methods that can alter the…

Because lists are mutable, we need to explicitly draw their folder when we visualize them. In this video we show how slicing affects these folders.

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.

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 session we do a deep dive in how we might design a series of functions to acomplish a single task.This class will be highly interactive. We will start with a specification – one more…

Objects have an interesting feature that we saw before we strings: they have methods in addition to functions. In this video we talk about those methods, and how they differ from string methods.

In the string videos we talked about the backwards approach to function design. Unforunately, this technique does not combine well with iterative testing. In this video we look at an alternative…

Both specifications and testing are critical for the first assignment. But many students struggle with them because they are so “fuzzy”.To help you improve your skills here, we have are…

This video series is where we start to pile on the vocabulary. In this video we reveiw the most important vocabulary terms for this series, and show you where to look if you are unsure about a word.

In this class we talk about how to import optional features into Python. We also show how to make program files we can run.This class will follow the same format as the last one. We will reinforce…
