NameError：名稱「TK」沒有在對象類

Question

我已經構建的應用程序定義的，源開始這樣的：

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 

但它最後一塊不能執行：

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

並且它給出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

在這種情況下我應該如何正確定義它？

你會錯過的import語句：from tkinter import Tk

，以避免衝突的最好辦法，就是要導入整個模塊，最終與一個別名，使之短（但不要忘記加上tk.無處不在，你已經叫做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()
