############### Blackjack Project #####################
# Difficulty Normal 😎: Use all Hints below to complete the project.
# Difficulty Hard 🤔: Use only Hints 1, 2, 3 to complete the project.
# Difficulty Extra Hard 😭: Only use Hints 1 & 2 to complete the project.
# Difficulty Expert 🤯: Only use Hint 1 to complete the project.
############### Our Blackjack House Rules #####################
## The deck is unlimited in size.
## There are no jokers.
## The Jack/Queen/King all count as 10.
## The Ace can count as 11 or 1.
## Use the following arr as the deck of cards:
## cards = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]
## The cards in the arr have equal probability of being drawn.
## Cards are not removed from the deck as they are drawn.
## The computer is the dealer.
##################### Hints #####################
# Hint 1: Go to this website and try out the Blackjack game:
# https://games.washingtonpost.com/games/blackjack/
# Then try out the completed Blackjack project here:
# http://blackjack-final.appbrewery.repl.run
# Hint 2: Read this breakdown of program requirements:
# http://listmoz.com/view/6h34DJpvJBFVRlZfJvxF
# Then try to create your own flowchart for the program.
# Hint 3: Download and read this flow chart I've created:
# https://drive.google.com/uc?export=download&id=1rDkiHCrhaf9eX7u7yjM1qwSuyEk-rPnt
# Hint 4: Create a deal_card() function that uses the List below to *return* a random card.
# 11 is the Ace.
import random
from art import logo
from replit import clear
print(logo)
def deal_card():
"""Returns a random card from [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]"""
cards = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]
return random.choice(cards)
# Hint 5: Deal the user and computer 2 cards each using deal_card() and append().
def blackjackCapstone():
user_cards = []
computer_cards = []
blackjack = 0
gameEnds = False
i = 0
for i in range(2):
user_cards.append(deal_card())
computer_cards.append(deal_card())
# Hint 6: Create a function called calculate_score() that takes a List of cards as input
# and returns the score.
# Look up the sum() function to help you do this.
def calculate_score(cards):
"""Returns the sum of all the items in arr 'cards'"""
ace, jack, blackjack = 11, 10, 0
if ace in cards and jack in cards:
return blackjack
if ace in cards and sum(cards) > 21:
cards.remove(ace)
cards.append(1)
return sum(cards)
return sum(cards)
# Hint 7: Inside calculate_score() check for a blackjack (a hand with only 2 cards: ace + 10) and return 0 instead of the actual score. 0 will represent a blackjack in our game.
# Hint 8: Inside calculate_score() check for an 11 (ace). If the score is already over 21, remove the 11 and replace it with a 1. You might need to look up append() and remove().
# Hint 9: Call calculate_score(). If the computer or the user has a blackjack (0) or if the user's score is over 21, then the game ends.

"""Takes both the user's score and the computer's score, compares the scores and returns the winner."""

c = calculate_score(computer_cards)
print(f"Your cards: {user_cards} = {u}")
print(f"Computer's cards: {computer_cards} = {c}")
print(compare(u, c))
# Hint 10: If the game has not ended, ask the user if they want to draw another card. If yes, then use the deal_card() function to add another card to the user_cards List. If no, then the game has ended.
# Hint 11: The score will need to be rechecked with every new card drawn and the checks in Hint 9 need to be repeated until the game ends.
# Hint 12: Once the user is done, it's time to let the computer play. The computer should keep drawing cards as long as it has a score less than 17.
# Hint 13: Create a function called compare() and pass in the user_score and computer_score. If the computer and user both have the same score, then it's a draw. If the computer has a blackjack (0), then the user loses. If the user has a blackjack (0), then the user wins. If the user_score is over 21, then the user loses. If the computer_score is over 21, then the computer loses. If none of the above, then the player with the highest score wins.
# Hint 14: Ask the user if they want to restart the game. If they answer yes, clear the console and start a new game of blackjack and show the logo from art.py.
