NameError：名称“TK”没有在对象类

Question

我已经构建的应用程序定义的，源开始这样的：

from tkinter import Text 
from tkinter import Label  

from AESEncDec import * 
from MD5Hashing import * 
from RSAEncDec import * 

color = 'lightblue' #color our background 

class Application(Frame): 

    def __init__(self, root=None): 

     Frame.__init__(self, root) 
     self.frame_width = 700 
     self.frame_height = 400 

但它最后一块不能执行：

#create object TK class 
the_window = Tk(className = " Cryptographic") 
#create object Application 
app = Application(the_window) 
#run our Application 
app.mainloop() 

并且它给出NameError：

Traceback (most recent call last): File "/home/artur/Documents/MScProject/MSc Project/Task #179276/main_program.py", line 169, in the_window = Tk(className = " Cryptographic") NameError: name 'Tk' is not defined

在这种情况下我应该如何正确定义它？

你会错过的import语句：from tkinter import Tk

，以避免冲突的最好办法，就是要导入整个模块，最终与一个别名，使之短（但不要忘记加上tk.无处不在，你已经叫做tkinter部件）：

import tkinter as tk 

from AESEncDec import * 
from MD5Hashing import * 
from RSAEncDec import * 

color = 'lightblue' #color our background 

class Application(tk.Frame): 

    def __init__(self, root=None): 

     tk.Frame.__init__(self, root) 
     self.frame_width = 700 
     self.frame_height = 400 


#create object TK class 
the_window = tk.Tk(className = " Cryptographic") 
#create object Application 
app = Application(the_window) 
#run our Application 
app.mainloop()
