Little experiment with ways to override generator method and the caveats associated with it in Python.

overriding_generator_method_oop.py

class base(object):
    def gen(self):
        for ii in [1,2,3]:
            yield ii
            
class child(base):
    def gen(self):
        for ii in [4,5,6]:
            yield ii

        super(child, self).gen()


b = base()
for x in b.gen(): print x

c = child()
for x in c.gen(): print x


# This does what you expect; yielding a generator object
# But then we would need multiple levels of looping and would be ugly to
# determine if the object that was returned (yielded) and then loop again;
# sounds like a weird recursion and infinite rabbit hole to achieve a correct
# and complete solution.

class child(base):
    def gen(self):
        for ii in [4,5,6]:
            yield ii

        yield super(child, self).gen()

# The 'correct' way to override generator method
class child(base):
    def gen(self):
        for ii in [4,5,6]:
            yield ii

        for ii in super(child, self).gen():
            yield ii
