Are you willing to use a setter function to set the variable? If so, 
it's trivial. This sort of thing is also commonly done for GUIs -- have 
a variable holder and set the variable's value via a setter function. 
Then you can automatically call callbacks or print the new value or 
whatever you want to do.

If not, I think you are out of luck for normal execution. The debugger 
might help, or perhaps deep knowledge of the internals of Python. I'm 
not familiar with either.
