Python Object-Oriented Python Inheritance Multiple Superclasses

Is treehouse python complier python2 or 3?

I've been practicing with the super() function but found out that the treehouse compiler doesn't accept super().method() since python2 requires format like super(ChildClass, self).method.

Why is that and is treehouse using the old python?

Treehouse uses Python 3. One obvious way to tell is that in Python 3, "print" is implemented as a function, but it is a keyword in Python 2.

Python 3 also uses "super", and it is covered in the courses. If you're having a specific problem with it, try starting a new question and be sure to include your code and a link to the course page (if any).

The Treehouse workspaces are using Python 3.5.0 by default. 

treehouse:~/workspace$ python                                              
Python 3.5.0 (default, Nov 28 2017, 19:33:11)                              
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux                           
Type "help", "copyright", "credits" or "license" for more information.     
>>> quit()                                                                 
treehouse:~/workspace$ python -V                                           
Python 3.5.0

Example code:

class Sup:
    def __init__(self, name="foo"):
        self.name = name

class Dep(Sup):
    def __init__(self):
        super().__init__(name="Depster")

Results:

treehouse:~/workspace$ python    
Python 3.5.0 (default, Nov 28 2017, 19:33:11) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux   
Type "help", "copyright", "credits" or "license" for more information. 
>>> from super_test import Sup, Dep   
>>> d = Dep() 
>>> d.name                                           
'Depster' 
>>> s = Sup()  
>>> s.name  
'foo'

Can you give a larger example of code that is not working for you? Perhaps snapshot your workspace and share the link.
