[frivolous]

i made a music player with a playlist but the songs in playlist are not playable because only the name of song is going in playlist not a complete mp3 file. can you tell me how to handle this problem?? here is my code

from Tkinter import *
import mp3play
import tkFileDialog
import Tkinter
import tkFont
import Tkinter as tk
#from PIL import ImageTk,Image

def open_file():                                #Opens a dialog box to open .mp3 file
    global music                                #then sends filename to file_name_label.
    global mp3
    global play_list
    filename.set (tkFileDialog.askopenfilename(defaultextension = ".mp3", filetypes=[("All Types", ".*"), ("MP3", ".mp3")]))
    playlist = filename.get()
    playlist_pieces = playlist.split("/")
    play_list.set (playlist_pieces[-1])
    playl = play_list.get()
    play_list_display.insert(END, playl)
    mp3 = filename.get()
    print mp3
    music = mp3play.load(mp3)
    pieces = mp3.split("/")
    name.set (pieces[-1])

def play():                                     #Plays the .mp3 file
    music.play()

def stop():                                     #Stops the .mp3 file
    music.stop()                

def pause():                                    #Pauses or unpauses the .mp3 file
    if music.ispaused() == True:
        music.unpause()
    elif music.ispaused() == False:
        music.pause()

def vol(event):                                 #Allows volume to be changed with the slider
    v = Scale.get(volume_slider)
    music.volume(v)

def tune_changed(event):
    idx = event.widget.curselection()[0]
    print ("Now playing %s" % event.widget.get(idx))
