깨달은 것

• 선택한 카드는 리스트로 만들어서 슬라이딩 & 나열 & 합산
• 점수비교 및 출력내용은 함수로 정의해서 깔끔하게 보이도록 코딩

##################### 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.
#cards = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]

#Hint 5: Deal the user and computer 2 cards each using deal_card() and append().
#user_cards = []
#computer_cards = []

#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.

#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.

#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.

sum()
the way that it works is we can put a literable, so like a list inside the parentheses as an input and then iy's going to add up all of the items in the list and it's going to return the total.

list.remove()
remove() searches for the first instance of the given element and removes it out of the list.

#11 is the Ace.
