How to get a random card from a deck of cards?

I have code of a generator that generates a deck of cards.
Now I want to get 1 random card from the deck and print it,
but it seems I can't do it.
Random.choice doesn't work for it.
i´ve tried to manually add the value + suit + color, but that doesnt work either.
Im new to coding and please forgive me for not understanding coding.
edit: translated to english.
from random import random
values = list(range(2,15))
suits = ["♣","♦","♥","♠"]
colors = ["black","red"]
#making the high value cards to the face of king, qeen, etc
face_cards = {
"J": 11,
"Q": 12,
"K": 13,
"A": 14,
11: "J",
12: "Q",
13: "K",
14: "A"
}
class card:
def __init__(self,value,suit,color):
self.value = value
self.suit = suit
self.color = color
#Makes the deck of cards in a cards []
def deck_of_cards(values, suits,colors):
cards = []
for value in values:
for suit in suits:
for color in colors:
if value in face_cards:
card_value = face_cards[value]
cards.append(card(card_value,suit,color))
else:
cards.append(card(value, suit,color))
return cards
ask = input("do you want a random card from the deck ?(yes or no): ")
cards = deck_of_cards(values,suits,colors)
if ask == "yes":
print("The random card is: ",random.choice(cards)) # This line is suposed to print 1 random card from the list cards,
# but the list doesnt seem to work the way i wanted it to work
else:
cards = deck_of_cards(values,suits,colors)
for card in cards: #This function is required to print the deck
print(card.value, card.suit,card.color)

You need to replace from random import random to import random, since the choice() function is located directly in the "random" module.
Also, for a good display of the selected map, you can override the __str__() method in the class card:
class card:
def __init__(self, value, suit, color):
self.value = value
self.suit = suit
self.color = color
def __str__(self):
return f'{self.color} {self.value} {self.suit}'

I tried out your code, and then made a few tweaks to provide a random selection of cards in the spirit of your project. Following is the code with the tweaks.
import random # Changed the import declaration
values = list(range(2,15))
suits = ["♣","♦","♥","♠"]
colors = ["black","red"]
#making the high value cards to the face of king, qeen, etc
face_cards = {
"J": 11,
"Q": 12,
"K": 13,
"A": 14,
11: "J",
12: "Q",
13: "K",
14: "A"
}
class card:
def __init__(self,value,suit):
self.value = value
self.suit = suit
if self.suit == "♣" or self.suit == "♠": # Stick to standard colors for suits
self.color = colors[0]
else:
self.color = colors[1]
#Makes the deck of cards in a cards []
def deck_of_cards(values, suits):
cards = []
for value in values:
for suit in suits:
if value in face_cards:
card_value = face_cards[value]
cards.append(card(card_value,suit))
else:
cards.append(card(value, suit))
return cards
cards = deck_of_cards(values,suits)
while True: # Allow for multiple selections
ask = input("do you want a random card from the deck ?(yes/no/quit): ") # Added a quit option
if ask == "quit":
break
if ask == "yes":
chosen = random.randint(0, 51) # Generate a random number
print("The random card is: ", cards[chosen].value, "of", cards[chosen].suit) # Then, get the card associated with that index
else:
cards = deck_of_cards(values,suits)
for card in cards: #This function is required to print the deck
print(card.value, card.suit,card.color)
First off, to make a random selection, a variable was added that would contain a random value between "0" and "51". This value would then be used as an index to your card deck to display the card. Also, in keeping with standard card deck colors, I removed the need to pass a color onto the card deck creation and just based the color on the usual and customary color of suits (e.g. "hearts" are red, "spades" are black). And I added a "while" loop so that a user can make multiple selections.
Give that a try and see if it meets the spirit of your project.

Trying To Develop a Scoring System for Blackjack Game

so I'm trying to make a scoring system using my current code for blackjack. The game is versus the computer and a player and the rules are a bit different , but that has all been setup. I need to purpose the code for scoring both player and computer's cards. I also should make it so an ace is set to be the value of 1, if to avoid busting. I was thinking of doing so as cards are drawn, but I'm not entirely sure. I tried cross class variables and I didn't find much success. Maybe I could fuse the player and deck classes?
Anyways, here is what I have, I'll provide any more information you need and there should be fairly thorough comments.
# This is a game of blackjack versus a computer.
# ------------------------------------------------------------------------------------------------------
# importing necessary files
import random
# A couple global variables for any necessary repeats and scoring.
RepeatCardChoice = 0
YourScore = 0
ComputerScore = 0
HitCount = 0 # The amount of times the player hits. Used for showing cards.
# Our deck itself.
class Card: # This is for developing the cards in the first place.
def __init__(self, suit, rank):
self.suit = suit
self.rank = rank
def show(self):
print(str(self.rank) + str(self.suit))
class Deck: # This is for deck behaviors and creating a deck.
def __init__(self):
self.cards = []
self.Cards()
def Cards(self):
for suit in ["S", "C", "D", "H"]: # S = Spades, C = Clubs, D = Diamonds, and H = Hearts
for rank in range(1, 14):
value = rank
if rank == 1:
rank = 'A' # Makes all 1 values = to ace.
elif rank == 11:
rank = 'J' # Makes all 11 values = to jack or j.
elif rank == 12:
rank = 'Q' # Makes all 12 values = to queen or Q.
elif rank == 13:
rank = 'K' # Makes all 13 values = to king or K.
if rank == (11) or (12) or (13):

self.value = value
self.cards.append(Card(suit, rank))

while count != CardCount:
count += 1
self.hand.append(deck.drawCard())
return self
def showHand(self, showCount): # Shows each card in the player's hand.

# Setting up the players.
Computer = Player("The Computer")
You = Player(PlayerName)
# Giving both players their hand to start off with.
Computer.draw(deck, 2)
You.draw(deck, 2)
# Here is where one card in each hand is shown.
print('You are showing:')
You.showHand(1)
print('The computer is showing:')
Computer.showHand(1)
# Here is where you decide to hit or stand.
while RepeatCardChoice == 0:
CardChoice = str(input('Hit (H) or Stand (S)?'))
if CardChoice == 'H':
You.draw(deck, 1)
HitCount += 1
You.showHand(1+HitCount)
RepeatCardChoice = 0 # This is so the player can keep deciding whether they still want to hit?
elif CardChoice == 'S':
RepeatCardChoice = 21 # Get it, because the winning score in blackjack is 21?
HitCount = 0
else:
RepeatCardChoice = 0
# Here is where we check your score.
if YourScore > 21:
exit('You busted and the computer wins!')
elif YourScore == 21:
exit('Blackjack, you win!')
# Here is where the computer hits or stands.
while ComputerScore <= 17:
Computer.draw(deck, 1)
HitCount +=1
Computer.showHand(1+HitCount)
if ComputerScore>21:
exit('The computer busted and you win!')
elif ComputerScore == 21:
exit('Blackjack, the computer wins!')
# Here is where we compare the scores to decide the winner.
if ComputerScore > YourScore:
exit('The computer wins!')
elif YourScore > ComputerScore:
exit('You win!')
elif ComputerScore == YourScore:
exit('You tied')
The output shouldn't provide any errors if the scoring system is successful, and I setup some variables that I might use to assign the score, however this can be changed as needed. Here is the output anyways.
What is your name?Sample
You are showing:
KC
The computer is showing:
JS
Hit (H) or Stand (S)?H
KC
8S
Hit (H) or Stand (S)?S
JS
...
Traceback (most recent call last):
File "Censored", line 119, in <module>
Computer.draw(deck, 1)
File "Censored", line 66, in draw
self.hand.append(deck.drawCard())
File "Censored", line 54, in drawCard
return self.cards.pop()
IndexError: pop from empty list
Essentially, what is happening is that the computer hits infinitely due to a lack of scoring, until there is nothing left to draw, this is after you stand. I skipped a lot of lines in the output, as they're just a bunch of cards getting drawn.

Global variable playing keeps getting name error

declared playing in my hit_or_stay function as a global variable but keep getting an error when i run my program saying "name error: playing is not defined" How do i fix this?
I used global playing in hit_or_stand() to control the gameflow depending on the player's input. When I run the code I get error "NameError: name playing is not defined." I tried to move "global playing" outside of hit_or_stay() but nothing seems to work.

NameError: name 'playing' is not defined

global in Python doesn't create a variable, it is defining the existing variable as global. So you are trying to state that a some variable is global (but it is still not exists) and then call it. So you get an error.
Please, never use global in Python! In 99.999% cases you can easily replace your code without any global variables! For example, add playing = True after this part of your code:
#GAMEPLAY
while True:
print("Welcome to Black Jack. Get as close to 21 as you can without going over 21.\n")
print("Dealer hits until he reaches 17. Aces count as 1 or 11\n")
#create an instance of Deck class and print the deck
game_deck = Deck()
#shuffle and print the deck
game_deck.shuffle()

The problem is that playing is defined in hit_or_stay, which isn't called until after the while loop begins.
Define playing as True to start, or include an explicit break condition
while True:
print("Welcome to Black Jack. Get as close to 21 as you can without going over 21.\n")
print("Dealer hits until he reaches 17. Aces count as 1 or 11\n")
# ~snip~
# define here
playing = True
while playing:
# rest of your code
Furthermore, it looks like hit_or_stay also has a while loop in it. I'd suggest taking a look at how you've structured your code so far and maybe refactoring it. Instead of just break in hit_or_stay, maybe you could return playing:
def hit_or_stay(deck,hand):
# no need for global playing anymore, as you return the proper bool
h_or_s = raw_input("Would you like to hit or stay? Enter 'hit' or 'stay': ")
if h_or_s[0].lower() == "h":
hit(deck,hand)
return True
elif h_or_s[0].lower() == "s":
return False
else:
raise ValueError("\nThere was an error. Try again.\n")
playing = True
while playing:
try:
playing = hit_or_stay(deck, hand)
# Catch the error for unexpected input and retry
except ValueError as e:
print(e)
continue

Simple card game in python

I am making a simple card game that deals the player two cards and if the cards are the same suit, the same rank (value), or a run the player wins. If the player's hand has none of these properties the player loses. The code I am using is as follows:
from itertools import product
import random
class Card(object):
FACES = {11: 'Jack', 12: 'Queen', 13: 'King', 14: 'Ace'}
def __init__(self, rank, suit):
self.suit = suit
self.rank = rank
def __str__(self):
value = self.FACES.get(self.rank, self.rank)
return "{0} of {1}".format(value, self.suit)
def __lt__(self, other):
return self.rank < other.rank
class Deck(object):
def __init__(self, ranks=None, suits=None):
if ranks is None:
ranks = xrange(2, 15)
if suits is None:
suits = ['Clubs', 'Diamonds', 'Hearts', 'Spades']
self.deck = []
for r in ranks:
for s in suits:
self.deck.append(Card(r, s))
def deal(self, n):
return random.sample(self.deck, n)
ranks = xrange(2, 15)
suits = ['Clubs', 'Diamonds', 'Hearts', 'Spades']
deck = Deck()
hand = deck.deal(2)
print "Your hand is"
print " - ".join(map(str, hand))
suits_in_hand = []
for card in hand:
suits_in_hand.append(card.suit)
if all(suits_in_hand == suit for suit in suits):
print "\nAll cards are of the same suit"
print "You Win!"
elif all(suits_in_hand == rank for rank in ranks):
print "\nAll cards are of the same rank"
print "You Win!"
# I don't know how to test if the cards in the player's hand are a run
else:
print "\nYou Lose."
However, even if the cards are both the same suit (e.g. 'two of Spades' and 'three of Spades') or the same rank (e.g. 'two of Hearts' and 'two of Clubs') it outputs You Lose. What can I do to fix this and how can I add the elif statement to test whether or not the cards in the player's hand are a run.

To check if all elements in a collection are the same, a short and elegant solution is to use a set :
suits_in_hand = set(card.suit for card in hand)
if len(suits_in_hand) == 1:
print "\nAll cards are of the same suit"
print "You Win!"
Same for ranks.
For runs, you could compare the set of ranks to a set from range :
ranks_in_hand = set(card.rank for card in hand)
min_rank == min(ranks_in_hand)
if set(ranks_in_hand) == set(range(min_rank, min_rank + 2)):
print "\nGot a run !"

Your main issue is you're trying to compare a single entity to an array, which you can't do. Instead of
if all(suits_in_hand == suit for suit in suits):
print "\nAll cards are of the same suit"
print "You Win!"
do something like
if suit in suits_in_hand for suit in suits:
print "\nAll cards are of the same suit"
print "You Win!"
For the ranks, you'll need to do something similar, but build a ranks_in_hand object.

You want to compare the elements in suits_in_hand against each other. Comparing them to suits is comparing your hand to all possible suits, which isn't right. Similarly, you need a ranks_in_hand and compare the elements in it to each other.
To check for a run, just check if the difference between the card ranks in your hand is 1.

For checking if all of the suits in the hand are the same, you can check to see if the length of the set created from suits_in_hand is one.
if len(set(suits_in_hand)) == 1:
# do something
A similar thing could be done for checking if the hand contains all of the same card.
To check for a run, you could try sorting the list and checking that each element is one greater than the next (simplified, just check the difference if you only need to support a hand size of two).

What you said doesn't really make sense . Hand is a class; player1 is an instance of that class. Translating into personal terms, this is parallel to asking how to send Brandon back to human so you can count his teeth. You don't: you simply use the tooth-counting procedure that works on all humans.
Looking specifically at your code, I think this deals with the line
player1.check(player1)
All it should need is
player1.check()
player1 is a Hand; this call goes to Hand's check method. Here, the object that invoked the method automatically shows up as the first argument, self. Get rid of the second one and just use
def check(self):
Does that clarify the point of confusion?

Check this code out, which is a working version of Go Fish executable and playable from the console. See how they use:
def makeTurn(self):
print '%s\'s hand: %s' % (self.name,self.displayHand())
chooseCard = raw_input('What card do you ask for? ').strip()
if chooseCard == 'quit':
sys.exit(0)
if chooseCard not in self.hand:
print 'You don\'t have that card. Try again! (or enter quit to exit)'
chooseCard = self.makeTurn()
return chooseCard
