I have a class with an attribute called 'gridsize' and I want
a derived class to force and keep it at 0.8 (representing 8mm).
Is this a correct, or the most pythonic approach?

Cheers,

Why not make gridsize a property with no set method?
André
Thanks for the suggestion, André.
I admit I haven't used properties, and had to look them up.
Pretty cool indeed ! But an extra unnecessary level of
complexity for my needs here, I feel.
They are _certainly_ going to become part of my
Python toolkit.
Cheers,
Ken.
