Help With BlackJack Game

aiiight (23)
So we have to create a modified blackjack game with a minimum of the functions I have in the code (no leeway for those)

If the users sum is > 21 they lose
if user sum = 21 they win
if user sum is under 21 and they don't want to go again, the user gets a hypothetical card. If said hypothetical card makes their total > 21 they win, if it makes their total < 21 they lose.

CurrentlyI still have a lot to do: I have to convert the numbers to strings (in print_card I should be printing the card in user friendly format by calling compute_face_name, which is supposed to return the face of the card in words. I'll worry about that later) I'm having a problem with passing values - I don't know how to add the next card's number to the current total, and how to print the total to the user.

EX.

Welcome to Blackjack! Below is your hand.
1
3
Your current total is 4
Would you like to test your luck? (y/n): y
13
Would you like to test your luck? (y/n): y
6
-----------------------------------------------------------

Above, after the number I want to be able to print their current total, and break if they are above 21... How could I do that?

Thank you!
