Suppose I have two classes: 'Jekyll' and 'Hyde' that are
related in a particular way.
When I create a Jekyll object, a Hyde one gets automatically
created (and displayed on a screen).
==== drum roll to announce Python script ===
Nice = Jekyll() # Nice_twin, a Hyde object, gets created.
Nice.doStuff() # Nice_twin is doing his own stuff
def subplot():
Evil = Jekyll() # Evil_twin gets created and displayed
Evil.doStuff() # Evil_twin does stuff on the screen
subplot()
#Evil.doMoreStuff() would raise an error, as it no longer exists
# in this namespace; however, Evil_twin still displayed
Nice.doMoreStuff() # continues to work.
==========End of script, and ask question=======
Evil_twin is still displayed on the screen at the end.
I would like for Evil_twin to disappear.
(I would like for this Hyde, to hide .... ok, bad pun!)
This morning I had the following thought:
I can, when I create a Jekyll object, update
an outside_list.
If, somehow, I could update that list when
a Jekyll object disappears
(perhaps by using __del__, which I have never touched)
that would solve my problem.
I could check outside_list each time I update
the screen display, and remove Evil_twin when
Evil no longer exists.
Any suggestions?
I've already tried lots of things, but nothing works properly.
Every attempt I make involves quite a bit of coding, as
the real-life situation is a bit more complicated than
what I explain here.
So, before I try again, I thought I would ask the
Collective Wisdom on this list.
