decorating base methods

I want to derive a base class, such that some methods are decorated.

The only thing I have in mind is:

class Base(object):
def A(self, x): pass
def B(self, y): pass

class Derived(Base):
@decorator
def A(self, x): Base.A(self, x)

Is this correct approach? How can avoid call to Base.A(...)?

Decorators are just syntactic sugar for calling a function, so for this
situation you probably want to ignore the sugar and use the decorator
directly:

class Derived(Base):
A = decorator(Base.A)
