![]()
Is there a way to make a class function unoverriddable? something like java's final keyword. i.e, any overriding class cannot override that method.

The issue is you are trying to write in Python using Java philosophies. Some thing carry over, but not all of them. In Python you can do the following and it is perfectly fine, but completely goes against how Java thinks of objects.
class Thing(object):
x = 1
something = Thing()
something.y = something.x
If you really want it, you can try the code posted here. But as you can see there is a lot of code there to get it to do what you want. It also should be noted that even the person that posted the code says it can be by passed using __dict__ or object.__setattr__.
