Actually I do it the other way around nowadays. I don't talk about class
object, instance object... I simply tell them to create attributes by
putting them in the __init__ . That way I simply avoid the explaination
until they actually need class attributes. By the time they need these
they are flying with their own wings.

When I would do it the other way around they would trip on the issue,
eventually, and than I would have to give the explaination, and this has
always been a difficult moment.
