Expose a class to Python and change it in Python as well

Question

I've used Boost.Python to expose my class into Python. I want to change this class or override some parts of it in Python as well as what we can do on classes in Python by default.

Answer 1

You should be able to make a subclass, like:

class Subclass(MyBoostPythonClass):
     # your modifications / extensions ...

Answer 2

It sounds like you want to subclass, which would be the other answer provided; however if you are looking to change an objects class on-the-fly, you could use object.__class__ = NewClass -- though this may be considered EVIL in some (probably most) circles.
