What is the proper way to create a class instance with an empty dictionary and/or list? [closed]

Question

This answer suggests I am creating my empty dictionary the correct way.

class Board:
    def __init(self):
        self.pot = 0
        self.activePlayer = 1
        self.activePlayers = 4
        self.passedPlayers = 0
        self.firstHand = True
        self.lastCardsPlayedList = []
        self.lastCardsPlayedDict = {}

    def playCard(self, cardInt, cardPic):
        self.lastCardsPlayedDict[cardInt] = cardPic
        self.lastCardsPlayedList.append(cardInt)
        self.lastCardsPlayedList.sort()

I create an instance of my class

b = Board()

but when I go to call it...

b.playCard(1, cardPic)

I get the error:

AttributeError: 'Board' object has no attribute 'lastCardsPlayedDict'

Silly Mistake...your init method is not defined correctly.

Here is the corrected code.

class Board:
    def __init__(self):
        self.pot = 0
        self.activePlayer = 1
        self.activePlayers = 4
        self.passedPlayers = 0
        self.firstHand = True
        self.lastCardsPlayedList = []
        self.lastCardsPlayedDict = {}

    def playCard(self, cardInt, cardPic):
        self.lastCardsPlayedDict[cardInt] = cardPic
        self.lastCardsPlayedList.append(cardInt)
        self.lastCardsPlayedList.sort()


b = Board()
b.playCard(1, 'cardPic')

print(b)
