Question

Use python write a function that checks the result of the blackjack game, given the sum of all cards in player 1’s and player 2’s hand in each round. For the i-th round, the i-th index of player1 list represents the sum of all cards of player1, and the i-th index of player2 list represents player2's card sum. The i-th index of the returned list should be the winner's card sum. If both players' card sums go over 21 in a round, we put 0 for that round to indicate that no one wins instead. You can assume two input lists always have the same length.

Example:

If player1’s list is [19, 25, 23], player2’s list is [20, 15, 25], the returned list should be [20, 15, 0]. Since in the first round, 20 is greater than 19 but not exceeds 21; in the second round, 25 exceeds 21 but 15 doesn’t; and in the third round, both 23 and 25 exceed 21.

def check_Blackjack(player1, player2):

    """

    >>> check_Blackjack([19, 21, 22], [21, 19, 3])

    [21, 21, 3]

    >>> check_Blackjack([17, 21, 22, 29], [15, 19, 3, 4])

    [17, 21, 3, 4]

    >>> check_Blackjack([], [])

    []
