It's unnecessary to use arguments when calling super for the parent class.

Explicitly passing in both the class and instance breaks the DRY (Don't Repeat Yourself) rule. This make the code brittle with regards to changing the class name, and is often considered inelegant by many.

As of Python 3, there is no need to explicitly specify the class name and instance when calling super(). If they are not provided, Python will default to the current class and the current instance.

Python 2.7 required specifying arguments, but note that Python 2.7 has already reached "End Of Life" and is no longer supported by the Python Software Foundation. For this reason your code might not need to support Python 2.7 either.

Moreover, it takes more than specifying arguments in super to make your codebase backwards compatible with Python 2.7: you must not use any new feature of Python 3...ever. That's some serious dedication to a dead language.

Given that these two are completely equivalent:

class FooBarClass(Bar):
    def foo(self):
        ...
        return super().foo()


class FooBarClass(Bar):
    def foo(self):
        ...
        return super(Foo, self).foo()

Why not choose the easiest to both read and write (the first one)?
