這是我第一次使用這個論壇，希望我能得到一個快速的迴應與詳細的解釋。 運行： 的Python 3.2 Tkinter的8.5 & Windows7的64tkinter中的循環 - 幫助！

我的代碼：

    def __init__(self, master): 
     super(Application, self).__init__(master)

     self.lbl2.grid(row = 0, column = 0) 
root = Tk() 
root.title("Program") 
app = Application(root) 
root.mainloop()

什麼我可以計算出如何做的，就是以某種方式使用一個循環，這樣，當全部9個是紅是它運行round_win（）函數。 IM不確定哪裏放環，以及如何編寫它（for循環，while循環，如果，但是，其他等） 感謝爲滿口任何幫助球員則可以提供:)

我從來沒有說過這是功課。我只是問，有人可以幫助循環部分。我做了一堆看，但沒有什麼是明確的，或者我不能將它分解成我自己的代碼（從僞代碼或其他人的例子）。 – James

作業與否，你需要重寫這個。你有沒有想過，因爲你在一行中複製和粘貼完全相同的功能___，可能有更好的方法來做到這一點？ – senderle

是的，我做到了。但我想不出一個辦法，沒有人問我幫助過我，我自己的方式也是如此。 – James

（這是我在stackoverflow的第一篇文章） 我認爲這樣的事情會工作。 您可以將原始按鈕放入列表中。 ...

def level_one(self): 
    ... 
    self.game_buttons = [] 

    for btn_index in range(9): 
     bg = "red" # change this to something based on the index 
     next_button = Button(self, bg = bg, width = 20, height = 10) 
     next_button['command'] = (lambda index=btn_index: self.callback(index)) 

     row = index/3 + 1 
     column = index % 3 
     next_button.grid(row = row, column = column, columnspan = 1) 
     self.game_buttons.append(next_button) 

def callback1(self, index): 
    button = self.game_buttons[index] 
    # add the appropriate code here 

def color_change(self, index): 
    # add the appropriate code here

此外，您還可以更改下面的代碼...

self.bttn_clicks2 += 1 
    if self.bttn_clicks2 == 3: 
     self.bttn_clicks2 = 1

到...

self.bttn_clicks2 = self.bttn_clicks2 % 3 + 1

你在正確的軌道上，但你需要閱讀：http://stackoverflow.com/questions/6737112/have-python-2-7-functions-remember-value-and-not-reference-closure-奇怪 – phkahler

+0

更改爲... （lambda index = btn_index：self.callback（index）） – jcfollower
