For the pure theory sake and mind expansion i got a question.
Experimenting with __new__ i found out how to create a singleton.
class SingleStr(object):
def __new__(cls,*args,**kwargs):
instance=cls.__dict__.get('instance')

Thanks Alex and Scott for your lead. It would've taken me forever
trying to figure it out by myself :)
I am affraid I didn't specify initially one thing and that led to a
confusion: there is no need to pick an instance from the weakref
dictionary, just return None if there are already 5 instances.
Thanks, Alex, again. The lesson has been taught. I appreciate very much
you spent time trying to help. Indeed the culprit of that infrequent
infinite loops was that bound reference "item" in the printing
loop. But frankly i thought that it only existed inside that loop.
Apparently I was wrong and g
I've been doing an application with Tkinter widgets. Nothing really
fancy just routine stuff. Though I have no problems with it by now I
guess it would be reasonable to ask about a thing that's been bothering
me a bit. Look at this piece of code:

Thank you all for your comments. They are priceless beyond any doubt.
As for the matter of the discussion it took me only a minute looking at
the code to realize that with Tkinter I pass "master" reference to
every widget and therefore I can access every method in the class
hierarchy. I'm a fool th
