问题描述：

我在烧瓶中制作一个tic tac toe用于学习目的。董事会被表示为字典，是一个全局变量。我想有一个“复位”板的按钮，使其可以再次播放，但是我的代码不起作用重置哪个执行，但板值不会改变。烧瓶重置全球词典

任何想法我做错了什么？非常感谢！

theBoard = {1:' ', 2:' ', 3:' ', 4: ' ', 5:' ', 6: ' ', 7:' ', 8:' ', 9:' '} 

@app.route('/reset', methods=["GET", "POST"]) 
def reset(): 
    for i in range (1,9): 
     theBoard[i] == ' ' 
    return render_template("test.html", theBoard=theBoard) 

@app.route('/play', methods=["GET","POST"]) 
def test1(): 
    return render_template("test.html", theBoard=theBoard) 

@app.route('/play1', methods=["GET", "POST"]) 
def test(): 
    if gameover(theBoard): 
     True 
     return 'the game is over1' 
    else: 
     x = request.form['move'] 
     move = int(x) 
     valid_moves = [1,2,3,4,5,6,7,8,9] 
    if move not in valid_moves: 
     return 'you did not specify a valid move, please try again!' 
    elif theBoard[move] != ' ': 
     return 'you can not play that space, it is taken' 
    else: 
     theBoard[move] = 'X' 
     if gameover(theBoard): 
      True 
      return 'the game is over2' 
     if winning_X(theBoard): 
     <and much more code - this part works>

您还可以分享您用于发布主板的标记的相关代码片段吗？ – joemurphy

@joemurphy我认为你的意思是HTML？（抱歉，我仍在学习）。上面加了 –

答

下面的代码是导致从我可以看到的错误：

theBoard[i] == ' '

以上实际上执行的比较不是将其更改为：

theBoard[i] = ' '

对不起还没有看到你的答案，一会儿回来！ –

答

HTML按钮调用其上执行/复位，但是板的值不改变。

def reset(): 
    for i in range (1,9): 
     theBoard[i] == ' ' # <--- This line 
    return render_template("test.html", theBoard=theBoard)

您使用==这是比较返回要么True或False，你想要什么=运算符（赋值运算符，一个等号），所以：theBoard[i] = ' '
