Python 中的井字游戏计算机，语法无效问题

Question

我才刚刚开始学习 Python。有人告诉我这将是一个很好的初学者项目。但是我运行在第 32 行遇到了一个无效的语法问题。我没有得到任何细节，但直到我在第 7 行创建列表时问题才开始出现。我之前的尝试是从第 12 行到第 20 行以及第 25 行到第 28 行，打印得很好。但这只是为了在可见板上放置移动。我仍然需要一种方法来跟踪该方块是否被占用，以及它如何影响计算机对未占用方块的偏好。不过我好像哪里做错了。

就连第31行和第32行的语法高亮都不一样，所以不管是什么问题，都是在第32行触发的（下图）。有人可以帮我理解这个问题吗？

import copy

def main():
    
    # Board squares list. String is either blank, O, or X. Int is adjusted bias.
    # Bool is whether or not the square is occupied, affects bias int.
    sq = [[" ", 0, False], [" ", 0, False], [" ", 0, False], 
    [" ", 0, False], [" ", 0, False], [" ", 0, False], 
    [" ", 0, False], [" ", 0, False], [" ", 0, False]]
    
    # DEBUG: Attempting to condense square attributes into a list.
    #sq_1 = " "
    #sq_2 = " "
    #sq_3 = " "
    #sq_4 = " "
    #sq_5 = " "
    #sq_6 = " "
    #sq_7 = " "
    #sq_8 = " "
    #sq_9 = " "
    
    # Board print, blank spaces and lines.
    board_blank = ["   |   |   " + "\n", "___|___|___" + "\n"]

    # DEBUG: Attempting to read squares from new list
    #board1 = " " + sq_1 + " | " + sq_2 + " | " + sq_3 + " " + "\n"
    #board2 = " " +  sq_4 + " | " + sq_5 + " | " + sq_6 + " " + "\n"
    #board3 = " " + sq_7 + " | " + sq_8 + " | " + sq_9 + " " + "\n"

    # Board print, updates with occupied squares after each move
    board1 = " " + sq[0][0] + " | " + sq[1][0] + " | " + sq[2[0] + " " + "\n"
    board2 = " " +  sq[3][0] + " | " + sq[4][0] + " | " + sq[5][0] + " " + "\n"
    board3 = " " + sq[6][0] + " | " + sq[7][0] + " | " + sq[8][0] + " " + "\n"

    # TEST: print board
    print_board(board1, board2, board3, board_blank)  

# Board printing function
def print_board(board1, board2, board3, board_blank):
    print((" " + board_blank[0]), board1, board_blank[1], board_blank[0], board2, 
    board_blank[1], board_blank[0], board3, board_blank[0])

# Acquire player's next move
def player_move():
    pass

# Calculate and execute computer's move
def comp_move():
    pass

main()

Answer 1

你在这一行中有语法错误

board1 = " " + sq[0][0] + " | " + sq[1][0] + " | " + sq[2[0] + " " + "\n"

# should be

board1 = " " + sq[0][0] + " | " + sq[1][0] + " | " + sq[2][0] + " " + "\n"
                                                         ^

Answer 2

您在第 31 行中缺少右方括号：

board1 = " " + sq[0][0] + " | " + sq[1][0] + " | " + sq[2[0] + " " + "\n"
                                                         ^

用以下内容替换该行：

board1 = " " + sq[0][0] + " | " + sq[1][0] + " | " + sq[2][0] + " " + "\n"
                                                         ^
