Python BlackJack

Background

A text-based implementation of BlackJack in Python. Uses a playing card deck class to preserve ranks and suits of cards. Which allows you to play with a single deck or multiple decks (it automatically reshuffles as needed). I built this to build Widrow's BlackJack Player and was rather disappointed with the python blackjack scripts I found crawling the web.
