You can cheat in your example by overriding the __str__ method. That method (or __repr__) is what gets called from the interpreter to display your variable. You can also override the __int__ method. Then int(i) can return a custom value. You can also do something close to what you want with properties: x = X() # Where X is a class with appropriate setter and getter methods x.i = 5 print x.i # Outputs something besides 5 However, it sounds like you want the equivalent of a non-existant __getvalue__ method that you could override to return a custom value instead of the one you initialised the variable with. Like a kind of "proxy to self" method. However, Python variables don't work that way :-) -- http://mail.python.org/mailman/listinfo/python-list
