如何在Python Rock，Paper，Scissors游戏中保持得分

Question

我正在用Python编写石头，剪刀，剪刀的游戏。游戏将继续循环播放，直到玩家选择退出为止。当玩家决定最终退出时，我想让程序打印玩家和计算机分数。我有以下代码，但是我写的分数计数器似乎不起作用。它仅显示1，其他两个为0。有人可以解释为什么会发生这种情况以及如何解决吗？

ValidPlays = ['r','p','s','q']
while PlayerChoice.lower() not in ValidPlays:
    print(PlayerChoice,'is not a valid play. Please enter a valid choice.')
    PlayerChoice = input('Your move: ')
while PlayerChoice != 'q':      
    from random import randint
    ComputerChoice = randint(1,3)
    CompMove = ''
    if ComputerChoice == 1:
        CompMove = 'r'
    elif ComputerChoice ==2:
        CompMove = 'p'
    else:
        CompMove = 's'
    print("Computer's move:",CompMove)

    RockWinMsg = 'Rock smashes Scissors!'
    PaperWinMsg = 'Paper covers Rock!'
    ScissorsWinMsg = 'Scissors cut Paper!'

    PlayerScore = 0
    CompScore = 0
    TieScore = 0

    if PlayerChoice.lower() == 'r' and CompMove == 'r':
        print('Tie!')
        TieScore = TieScore +1
    elif PlayerChoice.lower() == 'r' and CompMove == 'p':
        print(PaperWinMsg)
        print('Computer wins!')
        CompScore = CompScore +1
    elif PlayerChoice.lower() == 'r' and CompMove == 's':
        print(RockWinMsg)
        print(PlayerName,'wins!')
        PlayerScore = PlayerScore +1
        PlayerScore = PlayerScore +1
    if PlayerChoice.lower() == 'p' and CompMove == 'r':
        print(PaperWinMsg)
        print(PlayerName,'wins!')
    elif PlayerChoice.lower() == 'p' and CompMove == 'p':
        print('Tie!')
        TieScore = TieScore +1
    elif PlayerChoice.lower() == 'p' and CompMove == 's':
        print(ScissorsWinMsg)
        print('Computer wins!')
        CompScore = CompScore +1
    if PlayerChoice.lower() == 's' and CompMove == 'r':
        print(RockWinMsg)
        print('Computer wins!')
        CompScore = CompScore +1
    elif PlayerChoice.lower() == 's' and CompMove == 'p':
        print(ScissorsWinMsg)
        print(PlayerName,'wins!')
        PlayerScore = PlayerScore +1
    elif PlayerChoice.lower() == 's' and CompMove == 's':
        print('Tie!')
        TieScore = TieScore +1


    PlayerChoice = input('If you would like to play again, enter your move, otherwise enter q quit: ')

print('Player Score:',PlayerScore)
print('Computer Score:',CompScore)
print('Ties:',TieScore)
