[Tutor] Variable Question

[FxItAL@aol.com]

Hello All,
   I'm sure this is an easy one but I am quite perplexed over it.  In the 
following script, how do I get the value of "optSound" out of the function to 
be used in another module.

Thanks for any help you can offer, Al

from Tkinter import *
import os
import glob
import string

root=Tk()
list=Listbox(root, width=30,exportselection=0)
scroll=Scrollbar(root, command=list.yview)
list.configure(yscrollcommand=scroll.set)
list.pack(side=LEFT)
scroll.pack(side=RIGHT, fill=Y)
os.chdir('C:\\windows\\media')
x=glob.glob('*.wav')
for item in x:
    list.insert(END, item)  

def test():
    items=list.curselection()
    items=map(int, items) 
    z=items[0]         
    optSound = "C:\\windows\\media\\" +x[z]



OKBut = Button(root, activebackground='GREY', text='OK', command=test, 
width=10)
OKBut.pack()
root.mainloop()
