'BlackJack' is my personal take on reimplementing Casino BlackJack. 'BlackJack' is CLI game.

1. If you are on Window, you need to open logic.py and, on line 6, replace os.system('clear') with os.system('cls'). Then you can run main.py
2. If you are on Mac or Linux, you just need to run main.py.

This demo didn't cover:

• BlackJack
• Split rule

• Improve OOP knowledge
• Override __repr__ to debug
• String format
• Do not import variables from A import x1 but practice A.x1 instead.
