Python 将函数结果打印到tkinter消息框中？

我已经写了很多年了，我一直都能在谷歌上找到答案，直到现在。我无论如何也做不到这一点

在此之前，我有几个不同国家的列表，以及十几个只为用户打印内容的函数，这里不相关

我使用tkinter创建一个输入框，用户可以在其中键入国家（输入被分配给typedCountry）。然后，我在mainProgram（）函数的每个列表中搜索国家，每次找到匹配的列表时，我都返回另一个函数。除了我希望mainProgram（）将信息返回到tkinter GUI框而不是终端之外，一切都正常工作。我已经和它斗争了好几个小时，但我找不到一种方法让它工作，我愿意接受任何建议，甚至大幅修改代码或使用tkinter以外的其他东西都可以

def mainProgram():
    typedCountry = e.get()
    Country = typedCountry.lower()
    print 'Your country is: ' + typedCountry + '\n'
    if Country in bannedCountries:
        banned(typedCountry)
    if Country in cpBannedCountries:
        cpBanned(typedCountry)
    if Country in skrillBannedCountries:
        skrillBanned(typedCountry)
    if Country in bacsCountries:
        Bacs(typedCountry)
    if Country in sepaCountries:
        sepa(typedCountry)
    if Country in eftCountries:
        eft(typedCountry)
    if Country in ltdCountries:
        ltd(typedCountry)
    if Country in marketsCountries:
        markets(typedCountry)

master = Tk()
e = Entry(master)
e.pack()
e.focus_set()
var = mainProgram()

def textBox():
    root = Tk()
    label = Message(root, textvariable=var)
    label.pack()
    root.mainloop()

b = Button(master, text = "Search", command = mainProgram)
b.pack()

mainloop()

下面是您需要的主要代码（例如，如果您希望在您的终端运行此代码）：

例如，只需更换：

或者最好加上：

lbl = Label(master)
lbl.pack()

在

e

行下，然后将

return

s替换为：

lbl['text'] = x

您不调用textBox函数。如果我正确理解了这个问题，那么调用的函数必须更新文本框标签。此外，您不需要将lower（）country发送给函数。代码的缩短版本

tkinter

应该只使用一个

Tk（）

来创建主窗口。其他窗口（子窗口、对话框、消息框）应使用

Toplevel（）

tkinter

应该只使用一个

mainloop（）

来控制所有的窗口和小部件-如果你有两个mainloop，那么它可能在

get（）

和

set（）

上有问题。顺便说一句：

tkinter

有标准的消息框：你知道每次“点击”后消息消失的方法吗？因为现在他们只是停留在那里，每次点击都会添加一个新的呼叫function@JosephHarari第二部分应该是每次调用函数时更新一个标签。我一直在玩弄你说的，你是对的，但这意味着只打印最后一个函数。如果一个国家/地区匹配了两个或多个定义，则标签不会显示所有定义，而是只显示最新的一个谢谢，但是我刚刚测试了此解决方案，它也在执行相同的操作（只是将信息返回到终端）。我想要的是，当用户点击“搜索”时，运行函数main程序，结果以guit显示给用户。当输入缩写列表中的国家时，标签在我的系统（Linux Salckware）上正确更新。如果它不能在您的系统上工作，那么这是一个操作系统特有的问题，我无法帮助您解决。
