[Scorpio]

hello everybody,

I am begginner in python. I wrote the code under and I don't understand why I have the error you can find under

from random import *

class CardGame (object):
    Color = ["heart", "diamond", "club", "spade"]
    Value = [2, 3, 4, 5, 6, 7, 8, 9, 10, "valet", "queen", "king", "ace"]

    def __init__(self):
        self.cards = []
        for A in Value :
            for B in Color :
                self.cards.append((A, B))

    def CardName (self, Card):
        return "{0} of {1}".format(Value[Card[0]], Color[Card[1]])

    def ShuffleGame (self):
        return shuffle(self.cards)

    def TakeCard (self):
        return self.cards.pop()

Error:
Traceback (most recent call last):
  File "/Users/nic/Desktop/python/Card_Game_2.py", line 22, in <module>
    Game = CardGame()
  File "/Users/nic/Desktop/python/Card_Game_2.py", line 9, in __init__
    for A in Value :
NameError: name 'Value' is not defined

Thanks for your help
