Let’s break down the solution for the simple Python program that simulates a game of 21 (blackjack capstone project):

1. Initialization:
   • The program begins by printing a welcome message and explaining the rules of the game.
   • It initializes two variables: player_score and computer_score to keep track of the scores of the player and the computer.
2. Game Loop:
   • The program enters a while loop, which will continue until the game ends.
   • Within the loop, it displays the player’s current score and asks whether the player wants to draw a card. The player’s response is stored in the draw_card variable after converting it to lowercase.
3. Player’s Turn:
   • If the player chooses to draw a card (“yes”), the program generates a random card value between 1 and 10 using random.randint(1, 10). This card value is added to the player’s score.
   • The program checks if the player’s score exceeds 21. If it does, the player has busted, and the game ends. A message is displayed, and the loop is terminated using break.
4. Player’s Decision:
   • If the player chooses not to draw a card (“no”), the program displays the player’s final score and exits the loop using break.
5. Computer’s Turn:
   • After the player’s turn, it’s the computer’s turn to play.
   • The computer will continue drawing cards as long as its score is less than 17. This simulates a basic strategy where the computer is more aggressive if its score is low.
6. Computer’s Final Score:
   • Once the computer’s turn is over, the program displays the computer’s final score.
7. Determining the Winner:
   • The program determines the winner based on the following rules:
     • If the player’s score exceeds 21, the computer wins.
     • If the computer’s score exceeds 21, the player wins.
     • If the player’s score is higher than the computer’s score, the player wins.
     • If the computer’s score is higher than the player’s score, the computer wins.
     • If both the player and computer have the same score, it’s a tie.
8. End of the Game:
   • The program prints the result of the game, whether it’s a win for the player, the computer, or a tie.

The solution provides a basic implementation of a 21 (blackjack) game, where the player and the computer take turns drawing cards and the winner is determined based on the scores. It demonstrates the use of while loops, conditional statements (if and elif), user input handling, random number generation, and score tracking to create a simple game simulation.

    print("Welcome to the Game of 21!")

            print("You drew a card with a value of", card)
            player_score += card

            if player_score > 21:
                print("Bust! Your score is over 21. You lose.")
                break
        elif draw_card == "no":

            computer_score += computer_card

    print("\nComputer's final score:", computer_score)

    # Determine the winner
    if player_score > 21:
        print("Computer wins!")
    elif computer_score > 21:
        print("You win!")
    elif player_score > computer_score:
        print("You win!")
    elif computer_score > player_score:
        print("Computer wins!")
    else:
        print("It's a tie!")
