How to create the status bar of GUI window with Tkinter?

I have been working on the interface application of Tkinter recently. I want to add a status bar at the bottom of the window to show the status of the program. What should I do?

improve the music downloader by yourself. It has the state function you mentioned, but it is similar to Consle, and the whole source code is moved here.

-sharp
imoport tkinter as tk
win=tk.Tk()

-sharp
def info():
    info_win=tk.Tk()
    info_win.title('')
    -sharp

-sharp
msg=tk.Button(win,text='',command=info)
msg.pack()

-sharp"" 
button['text']=''
Menu
