metaclass ???

[BruceKL WhoH]

Mike C. Fletcher:

	Thanks,I have downloaded your pdf and code. But I'm still confused.
    What I'm trying to do is :
    I want to make two class, they are just subtly different,for example

class A:
    def f(self):
        print 'a'
    ...#other codes

class B:
    def f(self):
        print 'b'
    ...#other codes

all other codes are identical,just f is different.
    So can I use meta-class here? Or I should do this by another way?

    BTW,your pdf is quite nice,how do you make it? Beamer,pdfscreen, or PPT ?
