    age=txtAge.get()
    gender=var.get()
    eye=txtEye.get()
    password=txtPassword.get()
    conpassword=txtConPass.get()

我的问题是，如果它们在另一个函数中，我如何从输入框中获取数据？所有输入框都在 CreateGUI() 函数中。我想将变量 txtName 等传递给 Create() 函数。这种方法正确吗？

GUI 编程通常在一个类中完成：

class SimpleApp(object):
    def createGUI(self):
        ...
        self.txtName=Entry(sideframe)
        self.txtName.grid(row=0,column=1)

    def create(self):
        ...
        name=self.txtName.get()

通过创建txtName的属性self，您可以在其他方法中使用 访问其值self.txtName。其他变量可以用同样的方法处理。

为您的 Entry 小部件提供一个 StringVar 实例来存储输入很有用。

  self.myStringVar = tk.StringVar()
  self.myEntryWidget = tk.Entry(self.myFrame,textvariable=self.myStringVar)
  self.myEntryWidget.grid(row=1,column=1)

然后在您调用的其他一些函数中：

  self.myStringVar.get()

这在类中会更好，因为它使 GUI 更易于管理。
