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 28.3 The yield Statement

Making iterator classes is hard. In this video, we show an alternative, allowing us to write the iterator as a ‘function”. This requires the addition of a new python statement, the yield…

Lesson 27.3 The GameApp Class

In this video we introduce the GameApp class, which is a class written by your instructor. In the last assignment you will be creating a subclass of the class to run your game. This video highlights…

Lesson 27.2 Animation Frames

The while-loop that drives the game is hidden. This is going to create some interest challenges, particularly when you need variables that carry over from animation frame to animation frame. In this…
