It means that the default values are evaluated at definition time. At that
time there isn't a variable 'self' defined. It would only work if the
defaults would be evaluated at the time the method is called, but that's
not how Python works.

What do you mean 'variables in the class namespace'? Which variable is in
the class namespace? Please note that you can access variables in the class
namespace:

class MyClass:

    a = 10
    b = 20
    
    def my_method(self, param1=a, param2=b):
        print param1, param2
