In Python, how do you change an instantiated object after a reload?

Let's say you have an object that was instantiated from a class inside a module. Now, you reload that module. The next thing you'd like to do is make that reload affect that class.

mymodule.py
---
class ClassChange():
    def run(self):
        print 'one'

myexperiment.py
---
import mymodule
from mymodule import ClassChange  # why is this necessary?
myObject = ClassChange()
myObject.run()
>>> one
### later, i changed this file, so that it says print 'two'

reload(mymodule)
# trick to change myObject needed here
myObject.run()
>>> two

Do you have to make a new ClassChange object, copy myObject into that, and delete the old myObject? Or is there a simpler way?

Edit: The run() method seems like a static class style method but that was only for the sake of brevity. I'd like the run() method to operate on data inside the object, so a static module function wouldn't do...
