Python Blackjack Game

Here are some special cases to consider. If the Dealer goes over 21, all players who are still standing win. But the players that are not standing have already lost. If the Dealer does not go over 21 but stands on say 19 points then all players having points greater than 19 win. All players having points less than 19 lose. All players having points equal to 19 tie. The program should stop asking to hit if the player gets 21 points.

Output should look like this:
