from Tkinter import *import tkMessageBox  def getInput(title, message):  def return_callback(event):    print('quit...')    root.quit()  def close_callback():    tkMessageBox.showinfo('message', 'no click...')  root = Tk(className=title)  root.wm_attributes('-topmost', 1)  screenwidth, screenheight = root.maxsize()  width = 300  height = 100  size = '%dx%d+%d+%d' % (width, height, (screenwidth - width)/2, (screenheight - height)/2)  root.geometry(size)  root.resizable(0, 0)  lable = Label(root, height=2)  lable['text'] = message  lable.pack()  entry = Entry(root)  entry.bind('<Return>', return_callback)  entry.pack()  entry.focus_set()  root.protocol("WM_DELETE_WINDOW", close_callback)  root.mainloop()  str = entry.get()  root.destroy()  return str
