blackjack()

i am making a blackjack game and to calculate the total of user cards and computer cards I used the variables total_u and total_c. I initialized the total_u and total_c in the global and i modified it in the usr_turn() but after that i cannot use it in comparision(), the total_u and total_c in comparison returns 0 .

thanks for any help

Answer 1

Use the global keyword inside usr_turn :

global total_u
global total_c

total_u = sum(users_cards)
total_c = sum(comp_cards)
