Create a class at run-time

[Michel]

I want to add a method to a class such that it can be invoked on
specifics instances.
You solution works (as well as Patrick's one), thanks !
I still have a question though. If I print the type of the self object
I get when my method is
called, I get "<class 'test.TestClass'>". I guess this is because the
method is defined as a class method.
This is ok in my case, but just out of curiosity, what should I do to
change this method to an instance method?

Thanks for your help,

Michel.
