Dear NG,
can somebody tell me how the work packages are scheduled to the workers?
From the code it seems to me like a a static distribution, ie each
worker gets the same amount of work, not taking into account if a faster
worker already finished all work packages.
Thanks,

That's probably not the elegant way...

I'm not sure if I understand the problem right, but there is a rule
of thumb:
Prefer delegation to inheritance. If you can use delegation, avoid
inheritance. Esp. on python, where (from the point of view of usage)
there is no distinction between delegation or inheritance
ef __setup1(self, arg1):
print "setup1"
def __setup2(self, arg1, arg2):

Or for different parameter lists which may have the same length my
suggestion would be:

self.__dict__.update(kw)

If you wrap all methods you can ignore the if-test. Instead of the

Just starting is easy:

Hi.
I have a problem with weak refs and bound methods. The best explanation for the
problem is a short bit of code. I have the three classes Wrapper, Foo and Bar:
import weakref
class Wrapper(object):
def __init__(self,x):
self.x = weakref.ref(x)
def __call__(sel
When I change the class Wrapper to following, the class Foo works:
class Wrapper(object):
def __init__(self,x):
self.func_name = x.func_name
self.x = weakref.ref(x.im_self)
def __call__(self,*args,**kwargs):
x = self.x()
