I have 2 classes: a and b. 'b' inherits from 'a'. How do i get class 'a' to print it's actual name? In the case below, it prints the name of the child class. 

```
class a():
    def __init__(self):
        print("a -> " + self.__class__.__name__)

class b(a):
    def __init__(self):
        super().__init__()
        print("b -> " + self.__class__.__name__)

bo = b()

```

prints:

```
a -> b
b -> b

```
