Checkbutton Onvalue always = 0 python

Question

因此，在我的程序中，我詢問用戶他們喜歡什麼樣的音樂和什麼樣的電影。我使用checkbuttons來評估每個類別，問題是按鈕的開/關值始終爲0（而不是按下時爲1）。這意味着我永遠不會打印出像「你點擊X」這樣的語句，因爲它從來沒有得到那個價值。

我試着讓音樂fcn中的變量不同於電影fcn中的變量，我試着將它改爲「if x = 0，打印您選擇了x」，但是這只是打印出所有這些陳述立即，而不是單獨的。我懷疑這與做一個fcn有關，因爲它在外面很好。但我不知道該怎麼做。 （我也知道這顯然不是一個HTML代碼片段，但我不能通過代碼示例將它帶入問題，因爲縮進&我是新來的stackoverflow，所以不知道還有什麼要做）

Answer 1

它看起來像從問題你叫TK（莖），並在程序.mainloop兩次。根據這個答案：Here這是一個明確的問題。當你實例化'top'時，你不需要調用Tk（），而需要調用Toplevel（）。當您以這種方式創建框架時，您也不需要在框架上調用主循環。我在下面更新了你的代碼，這似乎工作得很好。

     C2Var = CheckVar2.get()

     C4Var = CheckVar4.get() 

     if C1Var == 1: 
      print "You like Moonlight!" 
     if C2Var == 1: 
      print "You like Les Choristes!" 
     if C3Var == 1: 
      print "You like Donnie Darko!" 
     if C4Var == 1: 
      print "You like Mommy!" 
    #end ChBoxSel() 

    top = Toplevel() 

    CheckVar1 = BooleanVar() 
    CheckVar2 = BooleanVar() 
    CheckVar3 = BooleanVar() 
    CheckVar4 = BooleanVar() 

    #CheckVar1.set(True)
