如何用不同的值更新相同的标签？

Question

   from tkinter import *import fndfrom fnd import fake_newsimport inferdef 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
