Lesson 30.6 The Partition algorithm

In the previous video, we saw that nested loops are causing our sorting algorithms to be slow. To speed things up, we need to get rid of one of these loops. To do that, we will need a special…

Lesson 29.4 The yield Statement

While generators are coroutines, the communication only goes one way: from the child to the calling parent. In this video we show how to reverse this communication, passing down information from the…

Lesson 26.2 While-Loop Traces

While-loops can do everything that a for-loop can (and more) but they are much harder to use. That is why, in this video, we talk about how to debug a while-loop before we talk about how to write…

Lesson 18.4 Nested Slicing

Slicing a list creates a copy. In this video we show what this means for nested lists. In particular, we show that sometimes a copy is not really a copy after all, and that we have to distinguish…

Lesson 18.1 List of Objects

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…

Lesson 16.6 Mutable For-Loops

Lists are mutables and support mutable functions. Many of these mutable functions contain for-loops. As we show in this video, this changes how we write the for-loop. In particular, we will not use…

Lesson 15.5 Slice Visualization

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.
