如何用不同的值更新相同的标签？

Question

   from tkinter import *

import fnd

from fnd import fake_news

import infer

def find_news():

    global e

    string = e.get()

    ans=infer.fake_fake(string)

    if(ans==0):

        w = Label(window, text="FAKE",bg="red",fg="white",font="none 19 bold")

        w.pack()

    else:

        w= Label(window,text="REAL",bg="green",fg="white",font="none 19 bold")

        w.pack()

window = Tk()

window.title('AVIS')

window.geometry("500x500")

window.configure(background='black')

l1=Label(window,text="",bg="black",fg="white",font="none 19 bold")

l1.pack()

l1.focus_set()

l=Label(window,text="Enter headline of news:",bg="black",fg="white",font="none 12 bold")

l.pack()

l.focus_set()

e = Entry(window,width=200)

e.pack()

e.focus_set()

b = Button(window,text='submit',command=find_news)

b.pack(side='bottom')

window.mainloop()

我从一个函数中得到一个答案，根据它我必须在标签中设置它是否为假。如何为同一标签设置不同的值。如果是假的，那它就是假的
