Question

我正在尝试根据youtube上的《聪明程序员》指南制作井字游戏。直到那一刻，一切都像在教程中一样顺利进行：

board = ['-','-','-',
         '-','-','-',
         '-','-','-',]

def display_board():
    print(board[0] + ' | ' + board[1]  + ' | ' +board[2])    
    print(board[3] + ' | ' + board[4]  + ' | ' +board[5])  
    print(board[6] + ' | ' + board[7]  + ' | ' +board[8])  


def play_game():
    # Display initial board
    display_board()


    handle_turn()


def handle_turn():
    position = input("Choose a position from 1-9: ")
    postion = int(position) - 1

    board[position] =  "X"
    display_board()



play_game()

是的，所以基本上，当他运行它时，他可以从1到9中选择一个数字，并且板上的减号之一更改为“ X”。当我这样做时，我遇到问题，控制台显示

"TypeError: list indices must be integers or slices, not str".

你能帮我吗？我不知道这是否重要，因为我确实是新手，但他使用的是python 3.6.1，而我使用的是3.7

Answer 1

您在handle_turn中有错字。更改为：

def handle_turn():
    position = input("Choose a position from 1-9: ")
    position = int(position) - 1

    board[position] =  "X"
    display_board()

Answer 2

您发布的代码段中有一个错字。下面是可变位置错误拼写的行。

代码行不正确

postion = int(position) - 1

更正的代码段

board = ['-','-','-',
         '-','-','-',
         '-','-','-',]

def display_board():
    print(board[0] + ' | ' + board[1]  + ' | ' +board[2])
    print(board[3] + ' | ' + board[4]  + ' | ' +board[5])
    print(board[6] + ' | ' + board[7]  + ' | ' +board[8])

def handle_turn():
    position = input("Choose a position from 1-9: ")
    position = int(position) - 1

    board[position] =  "X"
    display_board()

def play_game():
    # Display initial board
    display_board()
    handle_turn()

play_game()

此代码可以正常工作。
