? ? ? ? 前面寫過python彈框的ctypes.windll.user32方法：https://blog.csdn.net/Gordennizaicunzai/article/details/78966694

該方法調用windows系統的user32組件，不是純python方法，且wser32的MessageBoxA使用不當會出現亂碼，不是很好用。這里介紹pythonic的彈框——tkinter.messagebox。

FUNCTIONS

showinfo(title=None, message=None, **options)
? ? ? ? Show an info message

注意，tkinter.messagebox默認主窗口是顯示狀態，我們彈框時它是多于的，需要隱藏。

            
              >>> import tkinter as tk
>>> from tkinter import messagebox as messagebox
>>> 
>>> messagebox.showinfo('彈框', '注意，主窗口未退出')
'ok'
>>> 
            
          

? ?

隱藏主窗口，函數要放在彈框前，否則無效：

showerror(title=None, message=None, **options)
? ? ? ? Show an error message

            
              >>> tk.Tk().withdraw()  # 隱藏主窗口
''
>>> messagebox.showerror('彈框', 'say something')
'ok'
>>> 
            
          

? ??

? ??
? ? showwarning(title=None, message=None, **options)
? ? ? ? Show a warning message

            
              >>> tk.Tk().deiconify()  # 顯示主窗口
''
>>> messagebox.showwarning('彈框', 'say something')
'ok'
>>> 
            
          

askokcancel(title=None, message=None, **options)
? ? ? ? Ask if operation should proceed; return true if the answer is ok

? ? ? ? 選擇確定/取消，返回值分別對應true/false，下同：

            
              >>> 
>>> tk.Tk().withdraw()  # 隱藏主窗口
''
>>> msg = messagebox.askokcancel('對話框', '請選擇')
>>> msg
False
>>> 
            
          

? ? askquestion(title=None, message=None, **options)
? ? ? ? Ask a question

            
              >>> 
>>> msg = messagebox.askquestion('對話框', '請選擇')
>>> 
            
          

? ??
? ? askretrycancel(title=None, message=None, **options)
? ? ? ? Ask if operation should be retried; return true if the answer is yes

            
              msg = messagebox.askretrycancel('對話框', '請選擇')
            
          

? ??
? ? askyesno(title=None, message=None, **options)
? ? ? ? Ask a question; return true if the answer is yes
? ??

            
               msg = messagebox.askyesno('對話框', '請選擇')
            
          

? ? askyesnocancel(title=None, message=None, **options)
? ? ? ? Ask a question; return true if the answer is yes, None if cancelled.

            
              >>> msg = messagebox.askyesnocancel('對話框', '請選擇')
>>> msg
True
>>> msg = messagebox.askyesnocancel('對話框', '請選擇')
