Tkinter(2.x 与3.X的区别)

1.包的引入

2.X下是

from Tkinter import *

而3.x是

from tkinter import *

否则，会报找不到tkinter的错误

Traceback (most recent call last):
  File "read_data_from_gui.py", line 1, in <module>
    from tkinter import *
ImportError: No module named tkinter

2.消息框

 # 2.X version
 from Tkinter import *
 import tkMessageBox

 def save_data():
     try:
         fileD = open("deliveries.txt", "a")
         fileD.write("Depot:\n")
         fileD.write("%s\n" % depot.get())
         fileD.write("Description:\n")
         fileD.write("%s\n" % description.get())
         fileD.write("Address:\n")
         fileD.write("%s\n" % address.get("1.0", END))
         depot.set(None)
         description.delete(0, END)
         description.delete(0, END)
         address.delete("1.0", END)
     except Exception as ex:
         tkMessageBox.showerror("Error!", "Can't write to the file\n %s" % ex)

 #3.x version
 from tkinter import *
 import tkinter.messagebox

 def save_data():
     try:
         fileD = open("deliveries.txt", "a")
         fileD.write("Depot:\n")
         fileD.write("%s\n" % depot.get())
         fileD.write("Description:\n")
         fileD.write("%s\n" % description.get())
         fileD.write("Address:\n")
         fileD.write("%s\n" % address.get("1.0", END))
         depot.set(None)
         description.delete(0, END)
         description.delete(0, END)
         address.delete("1.0", END)
     except Exception as ex:
         tkinter.messagebox.showerror("Error!", "Can't write to the file\n %s" % ex)
