音樂播放器的播放列表

Question

我犯了一個音樂播放器，播放列表，但因爲只有首歌的名字在播放列表不是一個完整的MP3文件將在播放列表中的歌曲無法播放。你能告訴我如何處理這個問題嗎？ 這裏是我的代碼：

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)) 

def Exit(): 
    exit() 

root = tk.Tk() 
root.title("EmoPlayer") 

root.configure(background='black') 

#root = Tk() 

root.geometry('300x100+750+300') 

filename = Tkinter.StringVar() 
name = Tkinter.StringVar() 
play_list = Tkinter.StringVar() 
menubar = Menu(root) 
filemenu = Menu(menubar, tearoff=0, bg="black", fg="Orange") 
menubar.add_cascade(label='File', menu = filemenu) 
filemenu.add_command(label='Open', command = open_file) 
filemenu.add_separator() 
filemenu.add_command(label='Exit', command = Exit) 
root.config(menu=menubar) 
open_file = Button(root, width = 6, height = 1, text = 'Mood',fg='Orange', bg='black') 
open_file.grid(row=0, column=3) 
play_button = Button(root, width = 5, height = 1, text='Play', fg='Orange', command = play, bg="black") 
play_button.grid(row=0, column=0, sticky = W) 
stop_button = Button(root, width = 5, height = 1, text='Stop',fg='Orange', command = stop, bg="black") 
stop_button.grid(row=0, column=1, sticky = W) 
pause_button = Button(root, width = 5, height = 1, text='Pause',fg='Orange', command = pause, bg="black") 
pause_button.grid(row=0, column=2) 
volume_slider = Scale(root, label='Volume', orient = 'horizontal', fg = 'Orange', command = vol, bg="black") 
volume_slider.grid(row=0, column=4) 
file_name_label = Label(root, font=('Comic Sans', 8), fg = 'Orange', wraplength = 300, textvariable=name, bg="black") 
file_name_label.grid(row=3, column=0, columnspan=8) 

play_list_window = Toplevel(root, height = 150, width = 100) 
play_list_window.title("Playlist") 
play_list_display = Listbox(play_list_window, selectmode=EXTENDED, width = 50, bg="Dark Slate grey", fg="Orange") 
play_list_display.bind("<Double-Button-1>", tune_changed) 

play_list_display.pack() 

play_list_window.mainloop() 



root.mainloop()

我看看你的代碼，因爲我還沒有和mp3play前工作，覺得很有意思。

這是我改變了：

1. 我把你的代碼在一個類中，這樣更容易和更清潔的方法之間共享變量。這也消除了與global混亂的需要。通常清理一下代碼，例如，分解過長的行。儘管如此，我試圖不改變你的代碼。
2. 增加了trackLocations列表，保持實際的文件路徑。
3. 添加加載上雙擊新文件在播放列表中

這是結果的線，我希望它能幫助：

ValueError異常：無效的字面INT（）與基地10：'指定的設備未打開或未被MCI識別。'

我也與此錯誤掙扎長谷歌搜索我在德國的一些論壇上發現了一些C++的人誰說，這是因爲ID3v2標籤與女巫MCI有問題的帖子後。

然後我使用mutagen - Python多媒體標記庫，在播放它之前從mp3中去掉標記，因爲那時我再也沒有遇到過這個錯誤。同樣，如果訴諸誘變劑，確保在剝離其標籤之前，mp3文件具有寫入許可。
