I very new to programming and Python and trying to create a basic card game. Im stuck at getting the card from players hand to the middle. I successfully removed the card from players hand, but having hard time getting it to the middle of the board.
This is my idea of the removecard function, that should remove the card from player and add it to the middle.
def removecard(self):
self.cards.pop()
self.middlecards.append(self.cards.pop())
self.howmanycards -=1
self.middlecardscount +=1
class Deck:
def __init__(self):
self.fulldeck = []
for a in suits:
for b in ranks:
self.fulldeck.append(Card(a,b))
def __str__(self):
showfull = ''
for a in self.fulldeck:
showfull +='\n' + Card.__str__(a)
return showfull
def shuffle(self):
random.shuffle(self.fulldeck)
def deal(self):
newcard = self.fulldeck.pop()
return newcard
class Hand:
def __init__(self):
self.cards = []
self.middlecards = []
self.howmanycards = 0
self.middlecardscount = 0
def addcards(self,a):
self.cards.append(a)
self.howmanycards +=1
def removecard(self):
self.cards.pop()
self.middlecards.append(self.cards.pop())
self.howmanycards -=1
self.middlecardscount +=1
class Hand:
def __init__(self):
self.cards = []
self.middlecards = []
def removecard(self):
self.middlecards.append(self.cards.pop())
hand = Hand()
hand.cards = ['1','2','3']
hand.removecard()
print(hand.middlecards)
This is a sample example of what you are trying to do

I'm relatively knew to Python, but I decided to create a high low card game using classes. Ive got the classes all setup and everything, but the only issue I'm having is when I try to see if the card from the playerHand is bigger or smaller than the one from nextCard. playerHand and nextCard are both tied to classes, and the error that I am getting is: TypeError: '>' not supported between instances of 'Person' and 'NextCard'.
There 100% is a better way to do this, but this is what I've got so far:
import random
class Card(object):
def __init__(self, suit, value):
self.suit = suit
self.value = value
def show(self):
print ("{} of {}".format(self.value, self.suit))
class Deck(object):
def __init__(self):
self.cards = []
self.build()
def build(self):
for suit in ["Spades", "Clubs", "Diamonds", "Hearts"]:
for value in ["Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King"]:
self.cards.append(Card(suit, value))
def show(self):
for card in self.cards:
card.show()
def shuffle(self):
for n in range(len(self.cards)-1,0,-1):
r = random.randint(0, n)
self.cards[n], self.cards[r] = self.cards[r], self.cards[n]
def drawCard(self):
return self.cards.pop()
class Person(object):
def __init__(self):
self.hand = []
def draw(self, deck):
self.hand.append(deck.drawCard())
return self
def show(self):
for card in self.hand:
card.show()
class NextCard(object):
def __init__(self):
self.nextcard = []
def draw(self, deck):
self.nextcard.append(deck.drawCard())
return self
def show(self):
for card1 in self.nextcard:
card1.show()
deck = Deck()
deck.shuffle()
human = Person()
playerHand = human.draw(deck)
newcard = NextCard()
nextCard = newcard.draw(deck)
play = input("Do you want to play High/Low? Y or N? ")
while play.lower()== "y":
card = playerHand
print("The current card is: ", str(card.show()))
guess = input("Guess H for high or L for low." )
if guess.lower()=="h":
if card > nextCard:
print("Congratulations! You guessed correctly! The next card was ", card)
play = input("Play again? Y or N? ")
if card < nextCard:
print("You lost! The next card was ", nextCard)
play = input("Play again? Y or N? ")
if guess.lower()=="l":
if card > nextCard:
print("You lost! The next card was ", nextCard)
play = input("Play again? Y or N? ")
if card < nextCard:
print("Congratulations! You guessed correctly! The next card was ", nextCard)
else:
print("The game is over.")
Any solutions or workarounds to the compare between classes problem would be much appreciated. This was coded in python 3.
Are these playerHand and nextCard classes ?
To compare two classes with < operator you need to do operator overloading.
But that is advance level python
In here the fault is maybe that you are not creating object of classes
you are only aliasing the class playerHand
to make a object of it do
card = playerHand()
But it won't fix the problem (probably)
please give me a inner look of the class (edit your question in brief)
Now consider how the big boys do it
add a < and > operator over-loader in your classes that you are trying to compare
for < add a __lt__() method in your class
for > add a __gt__() method in your class
those __lt__() and __gt__() will do the overloading of operator
** (overloading means programming operators for custom use) **
In your code you need to add them in class Card and class Person
class Card(object):
def __init__(self, suit, value):
self.suit = suit
self.value = value
def __gt__(self, comparing_card):
# result is gonna be a boolean value
# the ace jack qween king will need some comparing basis
# work on it
result = self.value > comparing_card.value
return result
def __lt__(self, comparing_card):
result = self.value < comparing_card.value
return result
def show(self):
print ("{} of {}".format(self.value, self.suit))
and another class
class Person(object):
def __init__(self):
self.hand = []
def __gt__(self, comparing_obj):
# result is gonna be a boolean value
result = self.hand[-1] > comparing_obj.nextcard[-1]
return result
def __lt__(self, comparing_obj):
# result is gonna be a boolean value
result = self.hand[-1] < comparing_obj.nextcard[-1]
return result
def draw(self, deck):
self.hand.append(deck.drawCard())
return self
def show(self):
for card in self.hand:
card.show()
And this is the last fragment where you compare your class
# here we need oparator overloading
# this initially means '> sign' will call card.__gt__(nextCard)
# > sign will call card's ___gt__ method and pass nextCard as a parameter
# ___gt__(nextCard) returns a boolean value that we feed to the if statement down there
if card > nextCard:
# in here the print shows the class node
print("Congratulations! You guessed correctly! The next card was ", card)
# change card to card.show()
play = input("Play again? Y or N? ")
well this is a very deep topic (if its hard to comprehend) and intermediate python stuff. you can try some online stuff to know about it briefly.
try this geeks for geeks tutorial:
https://www.geeksforgeeks.org/operator-overloading-in-python/
Okay so i'm having issues with comparing a user inputted value with that already printed into the command line.
The printing to the command line is controlled by the classes that are called and i believe that it's causing issues with the process!
fairly sure i need to use def but i'm new to all of this so i don't know where to start!
Thanks for any help ahead of time! Not sure if this is the best way to go about creating a card game as it's pretty convoluted let me know your thoughts!
Originally tried to convert the hand of cards (bob.showHand) into a string but because it's being generated by a class it doesnt work? It's not much code so i've dumped it all below hope that's fine!
print('Running')
import random
class Turn:
def __init__(self, start):
self.start = start
class Card:
def __init__(self, suit, val):
self.suit = suit
self.value = val
def show(self):
print('{} of {}'.format(self.value, self.suit))
class Deck:
def __init__(self):
self.cards = []
self.build()
def build(self):
for s in ['Spades', 'Clubs', 'Diamonds', 'Hearts']:
for v in range(1,14):
self.cards.append(Card(s, v))
def show(self):
for c in self.cards:
c.show()
def shuffle(self):
for i in range(len(self.cards) - 1, 0, -1):
r = random.randint(0, i)
self.cards[i], self.cards[r] = self.cards[r], self.cards[i]
def drawCard(self):
return self.cards.pop()
def draw(self, deck):
self.hand.append(deck,drawCard())
return self
class Player1:
def __init__(self, name):
self.name = name
self.hand = []
def draw(self, deck):
self.hand.append(deck.drawCard())
return self
def showHand(self):
for card in self.hand:
card.show()
class Player2:
def __init__(self, name):
self.name = name
self.hand = []
def draw(self, deck):
self.hand.append(deck.drawCard())
return self
def showHand(self):
for card in self.hand:
card.show()
print('generating deck')
deck = Deck()
print('shuffling deck')
deck.shuffle()
bob = Player1('bob')
ryan = Player2('ryan')
print('dealing deck')
for x in range(7):
bob.draw(deck)
for y in range(7):
ryan.draw(deck)
Turn.start = 0
if Turn.start == 0:
print('bob to act')
print("bob's hand below")
print(bob.showHand())
cardplay = input('Type the card to play it')
if cardplay == bob.showHand():
print('playing card!')
I'd expect the print of playing card to appear. However no matter how much i try i can't seem to get it too work!
Your showHand method does not create a string; it causes print to be used to display text in the terminal. input reads a string from the user, and stores it. The == comparison will never compare equal, because on one side you have a string, and on the other side you have the special value None.
You should not have the methods of any of your classes do any print calls. Instead, have them return the appropriate strings, which are then printed from outside.
Also, by using a special name for these methods - __str__ - we can make Python use it automatically when printing a class instance, or when converting to string using str. Consider the example:
class Card:
def __init__(self, suit, val):
self.suit = suit
self.value = val
def __str__(self):
return f'{self.value} of {self.suit}'
class Hand:
def __init__(self, cards):
self.cards = cards
def __str__(self):
return ' | '.join(str(card) for card in self.cards)
my_hand = Hand([Card('Spades', 'Ace'), Card('Diamonds', 'King')]) # blackjack!
print(my_hand) # we see: `Ace of Spades | King of Diamonds`
Your problem is that if cardplay == bob.showHand(): does not actually do what you think. showHand() returns None and that will never equal any input Card. You need to convert what the user inputs to a card and then compare that card to the cards the Player is currently holding.
To solve these issues and make your code do what you are trying to do, change your Card Class to the following:
class Card:
def __init__(self, suit, val):
self.suit = suit
self.value = val
def show(self):
print('{} of {}'.format(self.value, self.suit))
def __eq__(self, other):
if (other.suit == self.suit and other.value == self.value):
return True
else:
return False
and the last couple of lines to this:
Turn.start = 0
if Turn.start == 0:
print('bob to act')
print("bob's hand below")
bob.showHand()
cardplay = input('Type the card to play it')
picked = Card(cardplay.split()[2], int(cardplay.split()[0]))
for card in bob.hand:
if picked == card:
print('playing card!')
Then, you can enter any Card, exactly as it appears, on the input line and it will print
'playing card!'
Im working through a blackjack game as an assignment for a python course I purchased on udemy and I believe I've found an issue with the class's provided solution. I made a change to the code myself to make it work, but I'd like to ask the stackoverflow community 2 questions: 1) Will someone please explain exactly why the solution doesn't work? I will make a few guesses below but as a beginner I'd like to understand exactly whats wrong for my own benefit. 2) Is the way I fixed the problem a good solution? If not, what are some other ways I could code this?
This is the given solution (I'm only showing the 3 classes of: Card, Hand and Deck - problem is within Deck, specifically Deck's str function)
# Let's start with defining our suits, ranks and values
suits = ('H','D','C','S')
ranking = ('A','2','3','4','5','6','7','8','9','10','J','Q','K')
card_val = {'A':1,'2':2,'3':3,'4':4,'5':5,'6':6,'7':7,'8':8,'9':9,'10':10,'J':10,'Q':10,'K':10}
class Card(object):
# card needs a suit and rank
def __init__(self, suit, rank):
self.suit = suit
self.rank = rank
def __str__(self):
return self.suit + self.rank
def get_suit(self):
return self.suit
def get_rank(self):
return self.rank
def draw(self):
print (self.suit + self.rank)
class Hand(object):
# A hand needs 2 cards and a total value
def __init__(self):
self.hand = []
self.value = 0
self.ace = False
def __str__(self):
hand_comp = ''
for card in self.hand:
card_name = card.__str__
hand_comp += " " + card_name
return 'The hand has %s' %hand_comp
def card_add(self, card):
self.hand.append(card)
# Check for Aces
if card.rank == 'A':
self.ace = True
self.value += card_val[card.rank]
def calc_val(self):
# calculate the value of the hand, make aces an 11 if they don't bust
if(self.ace == True and self.value < 12):
return self.value + 10
else:
return self.value
def draw(self, hidden):
if hidden == True and playing == True:
#Don't show first hidden card
starting_card = 1
else:
starting_card = 0
for x in range(starting_card, len(self.hand)):
self.hand[x].draw()
class Deck(object):
def __init__(self):
self.deck = []
for s in suits:
for r in ranking:
self.deck.append(Card(s,r))
def shuffle(self):
random.shuffle(self.deck)
def deal(self):
single_card = self.deck.pop()
return single_card
def __str__(self):
deck_comp = ''
for card in self.hand:
deck_comp += " " + deck_comp.__str__()
return "The deck has " + deck_comp
My problem is with the def str function under class Deck. The solution asks the program to run a for loop over... self.hand (which is under class Hand). I don't see why this would work at all. self.hand doesn't have anything to do with getting a full deck returned to me. Secondly, is deck_comp += " " + deck_comp.str() good code? I find my program freezes up if I only changed the loop to self.deck. I created a new variable called cards_name and assign it to cards.str() to get each card's suit and rank instead.
this is what I corrected the code to:
def __str__(self):
deck_comp = ''
for card in self.deck:
cards_name = card.__str__()
deck_comp += " " + cards_name
return "The deck has " + deck_comp
I'm making a Blackjack game and still early process. When I run my program, I get the error
im = Image(Point(350, 250), "playingcards/" + suit + str(rank) + ".gif")
NameError: name 'suit' is not defined
Which I'm pretty sure it's because im = ___ is in my def main(): part of my function, even though the suit is being defined within my code.
It's basically seems like my program is ignoring all of my code and going straight to the def main(), which is probably an ordering error on my part, but can someone explain where it's supposed to go so that it reads all my class functions before the main?
Here's my code:
from random import *
from graphics import *
class PlayingCard:
def __init__(self, rank, suit):
self.rank = rank
self.suit = suit
def getRank (self):
return self.rank
def getSuit(self):

def BJValue (self):
if self.rank == 'Ace':
return 1
elif self.rank == 'Jack' or self.rank == 'Queen' or self.rank == 'King':
return 10
else:
return int(self.rank)
def __str__(self):
suit_name= {'S':'Spades', 'C':'Clubs', 'D':'Diamonds', 'H':'Hearts'}
rank_name=[None, 'Ace','2','3','4','5','6','7','8','9','10','Jack','Queen','King']
return '%s of %s' % (Card.rank_names[self.rank], Card.suit_names[self.suit])

self.cards.append(card)
def shuffle(self):
random.shuffle(self.cards)

return self.deck.pop(0)

self.DealCard.dHand = [2]
self.DealCard.pHand = [2]
# PlayingCard.draw(win)

print('hi')
def main():
win = GraphWin("BlackJack", 800, 800)
im = Image(Point(350, 250), "playingcards/" + suit + str(rank) + ".gif")

i'm new to OOP and I've been stuck in writing this for the past hour. I just don't understand how to assign the deck I created to 2 players !
Classes
class Card:
def __init__(self, faceNum, suitNum):
self.faceNum = faceNum
self.suitNum = suitNum
def getCardName(self):
nameSuit = ['Ace','2','3','4','5','6','7','8','9','10','Jack','Queen','King']
nameFace = ['Coeur','Pique','Carreau','Trèfle']
return "%s of %s" % (nameFace[self.faceNum], nameSuit[self.suitNum])
def __str__(self):
carte_print1 = str(self.faceNum)
carte_print2 = str(self.suitNum)
return carte_print1 +('-')+ carte_print2
class Player:
def __init__(self,ID,Card):
self.PlayerID = ID
self.CardForPlayer = Card
Main code
import random
playerA = list()
playerB = list()
deck = list()
def deck():
deck = []
for suitNum in range(13):
for faceNum in range(4):
deck.append(Card(faceNum, suitNum))
return deck
deck = deck()
random.shuffle(deck)
for card in deck:
print(card.getCardName())
Now I just need to give 2 player an equal amount of cards how do I do this ?!
So there should be an attribute in the Player class with the name like deck. Modify your Player class like this.
class Player:
def __init__(self,ID,deck):
self.PlayerID = ID
self.deck = deck # this will hold a list of Card objects
Now in your main code, at the end of what you've written, add the following lines.
player1 = Player(1, deck())
player2 = Player(2, deck())
