Difference between super() and super (className,self) in Python

I have code snipped like : 

class A:
    def test(self):
        return 'A'

class B(A):
    def test(self):
        return 'B->' + super(B, self).test()

print(B().test())

Output : B->A

If I write something like this then I'm getting the same output : 

class A:
    def test(self):
        return 'A'

class B(A):
    def test(self):
        return 'B->' + super().test()  # change to super()


print(B().test())

In both cases I'm getting the same output. Then, I want to know what's the difference between this two types of calling of super? What are the pros and cons of using either of them?

In Python 2, only the super(className,self) syntax was possible. Since It was the most used version, as of Python 3 providing no arguments will act the same.

There are two typical use cases for super. In a class hierarchy with single inheritance, super can be used to refer to parent classes without naming them explicitly, thus making the code more maintainable
