If a class Child inherits from Parent, how to implement Child.some_method if Parent.some_method() returns Parent instance ?

Consider the following:
########################################
class Parent:
def some_method(self):
return Parent(...)
class Child:
def some_method(self):
...
return Parent.some_method(self)
########################################
Or Simply:
########################################
class Parent:
def some_method(self):
return Parent(...)
class Child:
pass
########################################
Child().some_method() returns a Parent instance.
We can rewrite Parent like this to avoid that
########################################
class Parent:
def some_method(self):
return self.__class__(...)
class Child:
def some_method(self):
...
return Parent.some_method(self)
########################################
But this style makes code full with ugly self.__class__
Any standard/pythonic way out there?
