For the two examples below:
(1)
class A:
... def foo(self):
... self.goo()
...
class B(A):
... def goo(self):
... print(1)
...
(2)
class A:
... def foo(self):
... self.goo()
... def goo(self): pass
...
class B(A):
... def goo(self):
... print(1)
...
Both can get the same result:
b = B()
b.foo()
1
What's the benefit of having the hook method goo() in class A in example 2?

None - as long as nobody tries one of those:
a = A()
a.foo()
or
class C(A):
def foo(self):
super().foo()
print(2)
c = C()
c.foo()
