+
+This code defines a `Deck` class to represent the deck of cards, with a `get_card` method that returns the next card from the deck and removes it from the deck. It also defines a `get_card_name` function to convert a card index to a string representation of the card, and a `get_hand_type` function to determine the type and relative strength of a 5-card hand. The `get_best_hand` function takes a board and hole cards and returns the best 5-card hand that can be made from them. The `calculate_equity` function takes a list of players' hole cards, an optional board and discards, and a number of trials, and uses Monte Carlo simulation to estimate the equity of each player's hand.
+
+
+
+To deal with situations where there are multiple players, external given part of the board cards, and extra discarded cards in the deck, the `calculate_equity` function takes additional arguments for the board and discards. The board cards and discards are removed from the deck before sampling new cards for the board or for each player's hole cards.

 The output of this code may vary because the equity calculation is based on Monte Carlo simulation, but it should be close to the correct equity values.
