Let's try a simple example.
Go back to the structure of an asse
_Python in a NutShell_, p. 138 has a bit on the assert statement which I
don't completely understand.
It says the syntax is

Thanks to Alans insights i have come up with a working class for a square,
overcomplicated probably but it lays the groundwork for my polygon class
