    else:
        tkinter.messagebox.showerror('tips', 'Error')

main = tkinter.Tk()
main.title('Hello tkinter')
main.geometry('300x200')

l1 = tkinter.Label(main, text='User name:')
l1.config(height=2)
l1.config(width=20)
l1.pack()

e1 = tkinter.Entry(main)
e1.pack()

l2.config(height=2)
l2.config(width=20)
l2.pack()
