Python and tkinter: NameError: name 'askyesno' is not defined

Question

我收到这个错误：

Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python36-32\lib\tkinter\__init__.py", line 1699, in __call__ return self.func(*args)
File "C:\Users\Administrator\Desktop\Base\utility.py", line 68, in clear
askyesno('Clear', 'Press YES or NO')
NameError: name 'askyesno' is not defined

当我尝试运行时：

if askyesno('Clear', 'Press YES or NO'):
 do some code

我已经尝试 tkMessageBox.askyesno 但仍然出现错误。

试试这个 from tkinter import messagebox 导入 messagebox 然后：

 if messagebox.askyesno('Clear', 'Press YES or NO'):
