[Python] Tkinter message box

python 2 已成為絕響，我們直接學習 python3 吧。

教學文章：
https://morvanzhou.github.io/tutorials/python-basic/tkinter/2-10-messagebox/

from tkinter import messagebox
messagebox.showinfo("Title", "a Tk MessageBox")

Tkinter showerror, showwarning and showinfo

Tkinter includes several other message boxes:

• showerror()
• showwarning()
• showinfo()

import tkinter
from tkinter import messagebox
hide main window
root = tkinter.Tk()
root.withdraw()
message box display
messagebox.showerror("Error", "Error message")
messagebox.showwarning("Warning","Warning message")
messagebox.showinfo("Information","Informative message")

請服用下面的 code 讓程式在 python2 & python3 都可以run:

try:

    # for Python2

    from Tkinter import *

    import ttk

    import tkMessageBox as messagebox

except ImportError:

    # for Python3

    from tkinter import *

    from tkinter import ttk

    from tkinter import messagebox
