Review

Write a function called divide_string(a_string), which takes a string as a parameter. Your function should return a string, which is the second half of characters from a_string followed by the first half of characters. 















  

    Write a function called count_uppercase(a_string),
    which takes a string as a parameter.  This function should return
    an integer, the number of upper case characters contained
    within a_string.
  

  


  

  

        
  

  





Blackjack



  If you don't know the card game blackjack, it's simple. Each player
  is dealt two cards. Face cards are worth 10 points, aces are worth
  11 points, and all other cards are worth face value. You can hit (ask for
  another card), or you can stand (keep the cards you currently
  have). You can continue this process as long as you want.  Once all
  players have stood, the player with the most points without going
  over 21 is the winner.




Details



  Create a Python functions
  called deal_blackjack_hand(deck) and 
  compute_blackjack_points(hand)in the
  file blackjack.py.  The dealer function function should
  take a list of strings, representing a deck of cards, and should
  return a list of strings representing a single hand
  of blackjack. This function should shuffle the deck, and "deal" the
  top two cards into the players hand.  The points function should
  take a list of strings representing the players hands, and should
  print the number of points the players hand contains.



Example


>>> import random
>>> deck = ['A♠', '2♠', '3♠', '4♠', '5♠', '6♠', '7♠', '8♠', '9♠', '10♠', 'J♠', 'Q♠', 'K♠',
            'A♣', '2♣', '3♣', '4♣', '5♣', '6♣', '7♣', '8♣', '9♣', '10♣', 'J♣', 'Q♣', 'K♣',
            'A♥', '2♥', '3♥', '4♥', '5♥', '6♥', '7♥', '8♥', '9♥', '10♥', 'J♥', 'Q♥', 'K♥',
            'A♦', '2♦', '3♦', '4♦', '5♦', '6♦', '7♦', '8♦', '9♦', '10♦', 'J♦', 'Q♦', 'K♦']
>>> hand = deal_blackjack_hand(deck)
>>> print(hand)
[10♦, K♠]
>>> points = compute_blackjack_points(hand)
>>> print(points)
20




Hint



  
  

    
    
      
  1. 
        
    
          The player's hand should be represented as a list of
          strings, just like the deck.  It should be initially empty.
          To deal a card to the player's hand, remove a card from the
          end of the deck by using the pop method and add
          the card to the end of the player's hand by using
          the append method.  You can use 
	  random.shuffle(a_list).
        
    
      
    2. 
      
  2. 
        
    
	  The compute_blackjack_points function should iterate over
          each string in the list and use a string slice to copy the
          rank of each card string.  It should convert each rank
          string into an integer and use an accumulator to compute the
          sum of all of the ranks.

Challenge

  

    This version of blackjack is 100% dependent on luck.  The way that
    skill becomes a factor in blackjack is in determining whether to
    hit or stay.
  

  

    After the player is dealt 2 cards, enter a loop that allows the
    player to add new cards to their hand, until the user choses to
    stay.
  

  
>>> import random
>>> deck = ['A♠', '2♠', '3♠', '4♠', '5♠', '6♠', '7♠', '8♠', '9♠', '10♠', 'J♠', 'Q♠', 'K♠',
            'A♣', '2♣', '3♣', '4♣', '5♣', '6♣', '7♣', '8♣', '9♣', '10♣', 'J♣', 'Q♣', 'K♣',
            'A♥', '2♥', '3♥', '4♥', '5♥', '6♥', '7♥', '8♥', '9♥', '10♥', 'J♥', 'Q♥', 'K♥',
            'A♦', '2♦', '3♦', '4♦', '5♦', '6♦', '7♦', '8♦', '9♦', '10♦', 'J♦', 'Q♦', 'K♦']
>>> random.shuffle(deck)
>>> play_blackjack_hand(deck)
Your Hand: [10♦, K♠]
Enter h to hit: h
Your Hand: [10♦, K♠, 2♥]
Enter h to hit: s
You have 22 points.
  







  
Challenge

  

    This solitary version of Blackjack is kind of boring. Add a dealer
    to the mix. The game is still very similar. At the beginning, you
    will deal cards to both the player and the dealer. You should
    display one of the dealer's cards to the player, as is typical
    with a game of blackjack.
  

  

    After the player hits until they are content, it is then the
    dealers turn. On the dealer's turn, repeatedly add cards to the
    dealer's hand until the total is 17 points or more.
  

  

    After the dealer's turn, you should show the entirety of the
    dealers hand, display the total points for both the player and the
    dealer, and print who won
  

  
>>> import random
>>> deck = ['A♠', '2♠', '3♠', '4♠', '5♠', '6♠', '7♠', '8♠', '9♠', '10♠', 'J♠', 'Q♠', 'K♠',
            'A♣', '2♣', '3♣', '4♣', '5♣', '6♣', '7♣', '8♣', '9♣', '10♣', 'J♣', 'Q♣', 'K♣',
            'A♥', '2♥', '3♥', '4♥', '5♥', '6♥', '7♥', '8♥', '9♥', '10♥', 'J♥', 'Q♥', 'K♥',
            'A♦', '2♦', '3♦', '4♦', '5♦', '6♦', '7♦', '8♦', '9♦', '10♦', 'J♦', 'Q♦', 'K♦']
>>> random.shuffle(deck)
>>> play_blackjack_hand(deck)
Dealer's Hand: 2♠ ##
~~~~~Your Turn~~~~~
Your Hand: 10♦ K♠
Enter h to hit: h
Your Hand: 10♦ K♠ 2♥
Enter h to hit: s
~~~Dealer's Turn~~~
Dealer hits.
Dealer's Hand: 2♠ 10♣ 8♥
Dealer stays.
You have 22 points.
Dealer has 20 points.
Dealer wins.
