main()Table(players, dealer, suits, ranks)-
players: A tuple of player tuples, where a player tuple is as
(name: str, bet: int)(Min. 1 player, Max. 5 players) - dealer: Name of the dealer as a string (Default: "Dealer")
- suits: A tuple of 4 suits (Default: ("Hearts", "Diamonds", "Spades", "Clubs"))
- ranks: A tuple of 13 ranks ace to king (Default: ("A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"))
- players: A tuple of PlayerSuper objects
- dealer: Dealer object
- deck: A list of Card objects in the deck
This object will be created from the method split() from the PlayerSuper object.
- name: Player name string

- play_hit(): This will deal an extra card to the player, returns the Card object for the card dealt
- play_stand(): This will stop further dealing of any cards to the player for the current round, returns a bool

-2: Player busts
-1: Player has less than the dealer
0: Player has the same total as the dealer and both are not bust
