Your Hand:
Ace Of Spades
Jack Of Spades
Count: 11

Should probably be a blackjack ;)

no ace = 1

and all face cards are 10

I wrote this 4 years ago as a quick hack to show a friend how Python classes work and to see if I could make Blackjack from memory. Do not assume this just works. <3

I tested it and it is an awesome game!!! It works just fine.
