更改label文本，Tkinter

Question

Here, is my code snippet:

def message(name, button):
    button['state'] = DISABLED
    mgs_label = ttk.Label(root)

   if button["text"] == "Encryption":

       mgs_label.pack_forget()
       mgs = encryption(name)
       mgs_label = ttk.Label(root, text=mgs).pack(side=LEFT)

   if button["text"] == "Decryption":

      mgs_label.pack_forget()
      mgs = decryption(name)
      mgs_label = ttk.Label(root, text=mgs).pack(side=LEFT)

When i am click the button whether it is encryption button or decryption button it is comes at mentioned position. Here is the snapshot: image1

And When i am click the another button the text comes after the previous one, i want to remove the previous text and then the last mgs should be displayed.

second snapshot: image2

Even i tried to make global variables but then the problem is encryption or decryption is done but the mgs is not showing on the GUI here is the code for that:

encryption_label = ttk.Label(root)
decryption_label = ttk.Label(root)
def message(name, button):
    button['state'] = DISABLED
    global encryption_label, decryption_label
    if button["text"] == "Encryption":

       if decryption_label.winfo_exists():
          decryption_label.pack_forget()

       mgs = encryption(name)
       encryption_label["text"] = mgs
       encryption_label.pack(side=LEFT)

    if button["text"] == "Decryption":

       if encryption_label.winfo_exists():
          encryption_label.pack_forget()

    mgs = decryption(name)
    decryption_label["text"] = mgs
    decryption_label.pack(side=LEFT)

I suggest creating the label only once and use label.configure to change the text. You should provide a working example instead of a code snippet. I made one for you. Thank you for your question.

import tkinter as tk
from tkinter import ttk
def e():
    message(None,x_button)
def d():
    message(None,y_button)
def message(name, button):
    #button['state'] = tk.DISABLED

    if button["text"] == "Encryption":
        mgs_label.configure(text = 'encrypted stuff')

    if button["text"] == "Decryption":
        mgs_label.configure(text = 'decrypted stuff')
  
root = tk.Tk()
x_button = tk.Button(root,text = 'Encryption',
                     command = e)
y_button = tk.Button(root,text = 'Decryption',
                    command = d )
mgs_label = ttk.Label(root)
y_button.pack()
x_button.pack()    
mgs_label.pack()
root.mainloop()
