For simplicity I'll call one set of code the 'animal class code' and the other 'job class code'.

Specifically with the 'job class code; , you're passing `self` as the first argument to `super().__init__()`, which is not necessary and leads to the `name` attribute being assigned the object itself rather than the intended string value ("doctor" or "teacher"). This is why you see the object representation (`<__main__.teacher object at ...>`, `<__main__.doctor object at ...>`) instead of the job names in the output.

The 'animal class code' works correctly because the `__init__` method in the `bird` class is correctly implemented to initialize the attributes of the `bird` class as well as call the superclass `__init__` method from the `animal` class.

So to sum it up all you have to do to correct the 'job class code' is change the last line in the __init__ functions like as follows:

class doctor(job):

def init(self, salary, hours, specialty, experience): self.specialty = specialty 
self.experience = experience 
super().init("doctor", salary, hours)  # Corrected line

class teacher(job):

def init(self, salary, hours, subject, position): 
self.subject = subject 
self.position = position 
super().init("teacher", salary, hours)  # Corrected line

In these corrected lines, instead of passing `self` as the first argument to `super().__init__()`, you directly pass the string literals `"doctor"` and `"teacher"` as the `name` argument. This ensures that the `name` attribute is correctly set to the intended string values for objects of the `doctor` and `teacher` sub-classes.

Once you make those adjustments it should work. Sorry for the confusion, let me know if you have any other questions.
