Yep, I strongly agree. Inheritance is overrated, as Guido says.
For what concerns the debate of multiple vs single inheritance, yes it
is true
that multiple inheritance is worse, but e

Yes : use composition + delegation. Python makes it easy:
#foo.py
class Commands(object):
def do_this(self,args):
...

Thanks both for suggestions. I still think that using inheritance is
somehow cleanest in this case (I always hear the mantra "avoid
multiple inheritance!", but this is one of the cases it seems to make
a lot of sense to me), but it's nice food for thought/code anyway.
Other suggestions are always

I had to solve the same problem recently, and I decided to avoid
multiple
inheritance by using delegation. My idea was to make the Cmd cla

It seems it works. It is not so straight-forward to me because I don't
know about new-style types and classes very well

Hi,
I am currently using the Cmd module for a mixed cli+gui application. I
am starting to refactor my code and it would be highly desirable if
many commands could be built as simple plugins.
My idea was:
- Load a list of plugin names (i.e. from the config file, or from the
plugins directory)
