回调python Tic Tac Toe代码

Question

所以我在这里有一个tic tac toe程序的代码

def playerID():
    # asks player if want x or y
    letter = ''
    while not (letter == 'X' or letter == 'O'):
        letter = input('Do you want to be X or O?').upper()

    # first tuple is player, second is computer
    if letter == 'X':
        return ['X', 'O']
    else:
        return ['O', 'X']

代码的后半部分是

while True:
    # resets the board
    theBoard = [' '] * 10
    playerLetter, computerLetter = playerID()
    turn = playFirst()
    print('The ' + turn + ' will go first.')

之后继续，但它是giving me two error's。我不认为这是区分大小写的。我对字符串或数组不是很好，有人能指出我在这里做错了吗？

我认为这是回调的问题，但当然我可以说出我的屁股。

您应该使用raw_input代替input来获取python 2.x中的string值
