Python2.7使用多个列表框作为菜单，需要从选择中调用函数

Question

我正在构建一个python2.7.14gui，并使用listbox作为菜单。我遇到的问题是能够从我列出的所有不同菜单选项中调用函数。我可以打印选择，我双击，但不能想出如何调用所有不同的菜单选择功能。我不应该使用列表框吗？你知道吗

from Tkinter import *


def onselect(evt):
    # Note here that Tkinter passes an event object to onselect()
    w = evt.widget
    index = int(w.curselection()[0])
    value = w.get(index)
    print 'You selected item %d: "%s"' % (index, value)
