Checkbutton的值Onvalue = 0 python

Question

因此，在我的节目中，我向用户询问他们喜欢什么样的音乐和什么样的电影。我使用检查按钮来评估这些类别中的每一个，问题是按钮的开/关值始终为0（而不是按下时为1）。这意味着我永远不会打印出像＆＃34这样的陈述;你点击了x＆＃34;因为它永远不会得到那个价值。

我试过让音乐fcn中的变量比电影fcn中的变量差，并且我尝试将其更改为＆＃34;如果x = 0，打印你选择x＆＃34 ;但是，这只是一次打印出所有语句，而不是单独打印出来。我怀疑它与fcn有关，因为它在外面工作正常。但我不知道该怎么做。

（另外我知道这显然不是一个HTML代码段，但我无法通过代码示例将其纳入问题，因为缩进和我对stackoverflow的新功能所以并不是＃39 ;确定还有什么可做的）

Answer 1

看起来这个问题源于你在程序中两次调用Tk（）和.mainloop。根据这个答案：Here这是一个明确的问题。在实例化'top'时，不需要调用Tk（），而是需要调用Toplevel（）。以这种方式创建框架时，您也不需要在框架上调用mainloop。我已经更新了下面的代码，这看起来效果很好。

from Tkinter import *

def movies():
    def chBoxSel():
        C1Var = CheckVar1.get()
        C2Var = CheckVar2.get()
        C3Var = CheckVar3.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)

    C1 = Checkbutton(top, text = "Moonlight(2016)", variable = CheckVar1,  \
                     onvalue = True, offvalue = False, height = 5, \
                     width = 20, \
                     command = chBoxSel)
    C2 = Checkbutton(top, text = "Les Chorites(2004)", variable = CheckVar2, \
                     onvalue = True, offvalue = False, height = 5, \
                     width = 20, \
                     command = chBoxSel)
    C3 = Checkbutton(top, text = "Donnie Darko(2001)", variable = CheckVar3, \
                     onvalue = True, offvalue = False, height = 5, \
