How to deal with Python2 and Super()?

So it is a common question. I am on my local machine, a MacBook Air (2011) with python2 pre-installed. Calling super() with no arguments gives me the following error:

TypeError at /teams/edit/1/ super() takes at least 1 argument (0 given)

  1. One solution I read was to include the class and self as two arguments in super(PageTitleMixin, self). This gives this error:

TypeError at /teams/edit/1/ must be type, not classobj

  1. Installing python3 should resolve this, but I cannot call manage.py with python 3: ModuleNotFoundError: No module named 'django.core.urlresolvers'

I cannot imagine that I'm the only one with this problem, yet I cannot find an easy solution. Advice is greatly appreciated. Thanks!

Python 2 is different from Python 3—the version Treehouse teaches—and many of Python 2's features are differently used than in Python 3. I recommend installing Python 3 on your computer.

I hope this helps!

Happy coding! :zap: ~Alex

This seems to work for me:

class PageTitleMixin(object):
    page_title = ""

    def get_page_title(self):
        return self.page_title

    def get_context_data(self, **kwargs):
        context = super(PageTitleMixin, self).get_context_data(**kwargs)
        context["page_title"] = self.get_page_title()
        return context
