For example you can add and remove methods and attributes from a class and change the base classes of a class. You can also modify individual instances of a class to change their attributes and behaviour independently of other instances of the class. What are you trying to do? For example see

thanks for links, I'll look at them.
Alan showed me some possibilities, i'm not quite sure how to initiate
modification and the way import keyword works in case of modified
imported modules.

my typical scenario is that my swing application is running, and i see
some error or chance for improvement - modify sources of app, stop and run
application again.
so task is to reload class defitions (from source files) and modify also
existing instances (their methods).
