Do you know about `__init_subclass__`?
It is called whenever a class is subclassed and can be used to

Well, it's definitely overkill for printing a dash instead of a zero,

I think that's a bit of overkill. The problem lies in the printing
part, but you're spreading the solution into the rest of the

On one the many mini-reports we use, we have a bunch of counts that are
frequently zero; because the other counts can also be low, it becomes
easy to miss the non-zero counts. For example:
Code Description
Conv Errors : 6

Argh. Thank you both. I'm glad it was simple!

Actually, scrape what I said.
I think you need to have metaclass in the class statement, not just meta.

Good Day!
I am stuck... hopefully a few fresh pairs of eyes will spot what I am
missing.
I have a metaclass, Traits, and two different testing files,
test_traits.py and tests.py. test_traits works fine, tests generates
the following error:

opaque to me... I also don't know why the example meta class is derived
from 'type'.
The project is to interchangeably replace an object with a similar group of
objects. The original project was not built

I have a class containing a series of classes like this:
class Th(Externaldevice):
class _Communicate(commandset2.CommandSet_Communicate):
def __getattribute__(self,attrname):
attr =
commandset2.CommandSet_Communicate.__getattribute__(self,attrname)
if "__call__" in dir(attr):
You're right I totally misunderstood it. And your idea is obvious and simple
enough :)
