Python Object-Oriented Python Dice Roller Giving a Hand

Posted by taejooncho

copied the code exactly from the video, but when I try Python runs NameError.

I copied the code from the video to WorkSpace, and when I try to do yh = YatzyHand() in the console python raise NameError saying the name 'args' is not defined...

I even downloaded the zip file to get the code from this video only to find that python is raising NameError again.

So, my question is what is wrong?? Why is python doing this?

m hands.py code was this

from dice import D6


class Hand(list):
    def __init__(self, size = 0, die_class = None, *args, **kwargs):
        if not die_class:
            raise ValueError("You must provide a die class")
        super().__init__()

        for _ in range(size):
            self.append(die_class())
        self.sort()


class YatzyHand(Hand):
    def __init__(self, *args, **kwargs):
        super().__init__(size = 5, die_class = D6, *args, **kwargs)

I am having the same issue mentioned above, as I am receiving a name error - @taejooncho, can you confirm that nothing else was changed prior to re-running the YatzyHand class?

Hello Mr.Freeman,

Thank you for your time and interest. I did not know what you meant by stacktrace output, so I just tried to do yh = YatzyHand() again and copy the entire NameError python was raising and post here, and I don't know if it is because I had to reload my workspace due to inactivity, but now it works!?

I did not change a thing, so...

Either way Thank you!

Denis, it might be best to start a new post and include your code.
