Question
I need some help fixing my code. This is a blackjack game and I am having a little trouble with when the player wins or loses. It is saying sometimes when the Player = 18 points and the Dealer = 23 points that the Player won when they didn't. I am a little stuck on this.

Explanation / Answer
No no no, If player = 18 and dealer = 23, then the Player wins as per the rule. So, the working is correct.
When you are playing a balckjack game, there is a rule of getting busted. When a total of the cards is greater than 21, whoever gets that total loses at the same time because the goal is to reach 21 or less but not more than that.
So, either a player or a dealer whoever is getting total of > 21 gets busted and loses the game. So this is completely valid execution.
Please comment if there is any query. Thank you. :)
