Iteration, selection and adding

[DPaul]

You have many questions, i think a start would be to put your deck in a dictionary type object like so:

deck = {'HA':11,'H2':2,'H3':3,'HJ':10}
print(deck['H2'])

I've included a few cards like Hearts/Ace, H 2, H 3, H Jack.... with the values they would have in blackjack.
With the key eg. 'HA', you can find the value and that leads to adding, etc.
