blackjack's Issues

Add Blackjack class

Attributes:

• deck: Deck()
• dealer: Dealer()
• players: list of Player() instances

Methods:

• Blackjack.play_game(): see rules below

  • This is what will be called in blackjack/__main__.py
  • Contains the main while loop to continue playing until done, asking players if they want to cash out, add more money, or continue
  • more to come...

• Blackjack.take_bets(): Take bets from Blackjack.players. Store info about bets in respective Player() classes

• Blackjack.deal(): Deal one card to each player.hand and then a facedown card to dealer.hand

• Blackjack.play_round(): Play a single round of blackjack. Call the Blackjack.players.player.play() Blackjack.dealer.play() methods

Add state + design for hidden (face down) Card

Need to add hidden attribute and design for planning + printing hidden card

Ignore coverage for main script

Add Role class

Do this before implementing player and dealer classes
✔️ Make sure there are tests before proceeding

Add Dealer class

• Dealer.play(deck: Deck) method
  • Unhide first card in Dealer.hand
  • Dealer.hit(card: Card) until Dealer.total >= 17

Add Player class

Attributes:

• bank: The amount of 💰 player has left
• bet: Amount player bet on a hand ♠️
• moves : {0: "hit", 1: "stay"} for now, maybe add more later
  Methods:
• self.choose_move(self):
  • Title-Case the moves for display
  • Return value from key-value
  • Isolating it like this makes testing easier
• self.play(self, deck: Deck):
  1. keep_playing = self.choose_move() == "hit" and self.total < 21
  2. while keep_playing
     • self.hit(card=deck.pop())
     • if self.total >= 21: break
     • keep_playing = self.choose_move() == "hit"

Deck will run out of cards eventually

Need to add a reshuffle method into Blackjack that gets automatically called in between rounds (if necessary)

Default Role.hand attribute to None

This way the Player() and Dealer() instances can be created before any cards are dealt. Needs to be the case if the players are going to make bets before getting dealt cards.

♻️ The Role.hand attribute needs to become a property with the @property.setter method that recalculates the Role.total each time a card is added.
♻️ Take the self.set_ace_value() out of Role.__init__()

Add tests for Blackjack.play_game() and setup_game

This is will a chance to bring code coverage back to 💯 and maybe even improve the test suite after reading my cool 😎 new ✨ pytest book 📖

Consider refactor of who wins round

A lot of logic in Blackjack.play_round() right now, especially with who wins the round -- consider moving this to a separate method Blackjack.determine_winner or something like that.

Add bust attribute to Role class

Boolean property (or attribute?) that determines whether or not the Role.hand >= 21

Add setup_game() utility function

Ask for inputs like

• How many players
• How much each player wants to play with

Returns

• A Blackjack instance ready to have Blackjack.play_game() called
