value=value

In the D6 class, Kenneth uses the super() function to call the init in the Die class. I don't understand why he passed value=value. Wouldn't just value be enough? e.g. super().init(sides=6, value)

What he's using is called keyword arguments. You can learn more about them below: https://docs.python.org/2/tutorial/controlflow.html#keyword-arguments

In the video he could have used this: super().init(6, value) but you can't use super().init(sides=6, value) because all positional arguments have to be first.

Hope that makes sense.

I should also add that using keyword arguments also has the added benefit to eliminate any "magic" value. What I mean by "magic" value is that if you look at your code in a few months or years, you might not know what that 6 was for. Or at least it makes it an easier read, so you don't have to check each of your methods/functions declarations to understand what's going on.
