Can't get my Labels to update in tkinter :   I'm trying to create a program in where you put a word in a box, press add, and this word goes to a list, which is also displayed on the right side. When I press the forward button the first thing on teh list is deleted. Problem is I can't get the labels to update when I press teh buttons / edit the list...

Thx in advance.  

    from tkinter import *
    
    root = Tk()
    root.title('Speakers List')
    root.minsize(800, 600)
    
    speakers = ['none']
    spe = speakers[0]
    
    def add():
        if spe == 'none':
            speakers.insert(0, [s])
            e.delete(0, END)
            spe.config(text=speakers[0])
        else:
            speakers[-2] = [s]
            e.delete(0, END)
            spe.config(text=speakers[0])
        return
    
    
    def forward():
        if len(speakers) is 0:
            return
        else:
            del speakers[0]
            spe.config(text=speakers[0])
        return
    
    
    entry = StringVar()
    e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
    e.grid(row=0, sticky=W)
    s = e.get()
    
    button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black', command=add)
    button1.grid(row=0, column=1)
    
    button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black', command=forward)
    button2.grid(row=1, column=1)
    
    n = Label(root, font=("Arial", 35), bd=2, text=spe)
    n.grid(row=1, sticky=W)
    
    listdisplay = Label(root, font=('Arial', 20), text=speakers)
    listdisplay.grid(row=0, column=10)
    
    
    root.mainloop()
