这样报错

import tkinter as tk
class jiemian(tk.Tk):
def __init__(self):
super().__init__()
self.createWidgets()
def createWidgets(self):
self.thelabel_number = tk.Label(self,text = '测试',relief = SUNKEN).pack()
if __name__ =='__main__':
jiemian = jiemian()
jiemian.mainloop()

复制代码

报错信息：
Traceback (most recent call last):
  File "E:/wzyPython/test_TK/ceshi.py", line 9, in <module>
jiemian = jiemian()
  File "E:/wzyPython/test_TK/ceshi.py", line 5, in __init__
self.createWidgets()
  File "E:/wzyPython/test_TK/ceshi.py", line 7, in createWidgets
self.thelabel_number = tk.Label(self,text = '测试',relief = SUNKEN).pack()
NameError: name 'SUNKEN' is not defined

这样就可以运行

from tkinter import *
class jiemian(Tk):
def __init__(self):
super().__init__()
self.createWidgets()
def createWidgets(self):
self.thelabel_number = Label(self,text = '测试',relief = SUNKEN).pack()
if __name__ =='__main__':
jiemian = jiemian()
jiemian.mainloop()

复制代码

import tkinter as tk：

from tkinter import *
