KeyError Message

[FantasyAres]

Hi, I am having an issue running the program. When I try to run, I get the following below.

---

python blackjack_original.py BasicStrategy.csv
Traceback (most recent call last):
File "blackjack_original.py", line 468, in
game.play_round()
File "blackjack_original.py", line 436, in play_round
self.player.play(self.shoe)
File "blackjack_original.py", line 261, in play
self.play_hand(hand, shoe)
File "blackjack_original.py", line 275, in play_hand
flag = HARD_STRATEGY[hand.value][self.dealer_hand.cards[0].name]
KeyError: 'Ace'

---

The KeyError is related to the cards dict? How can I resolve? Thank you

This error occurs when the:
HARD_STRATEGY = {}
SOFT_STRATEGY = {}
PAIR_STRATEGY = {}
are empty - this is a result of loading an invalid CSV file. See the other post related to " INDEX" error for comments on correctly loading the csv file via the importer.

SOLUTION FOR INDEX ERROR in other post:

This is the expected behavior, the sys object receives arguments when calling the script from the command line.
sys.argv[1] is the first argument passed - it should be the name/path to the Strategy.csv file.
EX: python blackjack_sim.py strategy.csv (assumes csv file in same directory as py file.)

In the alternativve, if you are running from within editor, you can remove the argv[1] and just hard code the file name/path:
EX: importer = StrategyImporter('BS.csv')
