tracks added

Pool Puzzle Solution

Your job was to take segments from the
pool and place them into the blank
lines in the code. You could not
use the same segment more than
once, and you didn’t need to use
all the segments. Your goal was to
complete the code in hfmix.pyw
so that it reads all the tracks from the
directory and then adds them to the GUI
interface.
from tkinter import *
You need to talk to the from sound_panel import *
import pygame.mixer
operating system, so import os
import the “os” module.
app = Tk()
app.title("Head First Mix")
Get the names of all
mixer = pygame.mixer the files in the current

mixer.init() directory.
T ake each of the
dirList = os.listdir(".")
filenames...
for fname in dirList:

if fname.endswith(".wav"):

...and if it ends in “.wav”... panel = SoundPanel(app, mixer, fname)

panel.pack()

...create a def shutdown():
SoundPanel() and add track.stop()
it to the GUI. app.destroy()
app.protocol("WM_DELETE_WINDOW", shutdown)
app.mainloop()

This wasn’t
needed.
