Abstraction
Abstraction is a key pillar in computer science theory and particularly object orientated programming. It involves filtering out – essentially, ignoring - the characteristics that we don't need in order to concentrate on those that we do.
Presentation on Abstraction
Abstraction in action - Python (Creating a universe with planets)
Watch this video lesson (in conjunction with the above presentation) for coded solutions and suggestions for teaching this topic with object orientated programming. https://youtu.be/6SR5hYhOVTg
