Liskov_example

Example of Liskov Substitution Principle (LSP) violation in Python.

Demonstration of LSP violation

The violation example has a subclass "Square" of a superclass "Rectangle". The Square class overrides the setter methods for height and width as a bodgy work-around which causes problems in the "multiply" base class function.

python -m liskov_badness

Demonstration of LSP correctness

The conformance example has a subclasses "Square" and "Rectangle" of a superclass "Polygon". The Square and Rectangle classes both implement their own getters and setters for height and width.

python -m liskov_conformance
