python scroll workaround

I tend to use labels for everything text-related in my python programs. After coding a very long label for about 50 references, I'm now stuck with a toplevel window with a multiple line label, requiring a scrollbar, and labels don't scroll.

I've got the scrollbar on the window, but it doesn't scroll. Is there a workaround to scroll up and down my 'text' label or do I need a different widget to put in my toplevel window?

        filewin = Toplevel(background="white")

        scrollbar=Scrollbar(filewin)
        scrollbar.pack(side=RIGHT, fill=Y)
        yscrollcommand=scrollbar.set 


        Label(filewin, text=". . .\n \

        justify=LEFT, background="white", foreground="black", wraplength=1000).pack()
        filewin.title("Matrix References")

You can not use a scrollbar with a label.
Use Text instead:

from Tkinter import *

root = Tk()

mytext = "Here_your very long text"

scrbar = Scrollbar(root, orient=VERTICAL)
scrbar.pack(side=RIGHT,fill=Y)

text = Text(root, width=80, height=10, state=NORMAL, background="white", foreground="black")
text.insert(INSERT, mytext)
text['state'] = DISABLED
text.pack()

text['yscrollcommand'] = scrbar.set
scrbar['command'] = text.yview

root.title("Matrix References")
root.mainloop()

This produces (You should maybe adapt the text format):
