一、环境设置
第一步引入必须的各类包

import osimport tkinterimport tkinter.filedialogimport randomimport timeimport threadingimport pygame |
特别是pygame需要手动安装
|

|
pip install pygame |
二、播放功能
首先选择音乐目录，然后创建播放现成，播放音乐。

# 播放按钮def buttonPlayClick(): # 选择要播放的音乐文件夹 global folder if not folder: folder = tkinter.filedialog.askdirectory() if not folder: return global playing playing = True # 创建一个线程来播放音乐，当前主线程用来接收用户操作 t = threading.Thread(target=play) t.start() # 根据情况禁用和启用相应的按钮 buttonPlay['state'] = 'disabled' buttonStop['state'] = 'normal' buttonPause['state'] = 'normal' buttonNext['state'] = 'normal' pause_resume.set('Pause')buttonPlay = tkinter.Button(root, text='Play', command=buttonPlayClick)buttonPlay.place(x=20, y=10, width=50, height=20) |
三、停止功能
很直接，直接停止播放，当然更改按钮状态也属常规操作。

def buttonStopClick(): global playing playing = False pygame.mixer.music.stop() musicName.set('暂时没有播放音乐') buttonPlay['state'] = 'normal' buttonStop['state'] = 'disabled' buttonPause['state'] = 'disabled' buttonNext['state'] = 'disabled' global folder folder = ''buttonStop = tkinter.Button(root, text='Stop', command=buttonStopClick)buttonStop.place(x=80, y=10, width=50, height=20)buttonStop['state'] = 'disabled' |
四、暂停与恢复
这个好理解，也是直接现成操作，加个判断，状态更改。

# 暂停与恢复，两个功能共用一个按钮def buttonPauseClick(): # global playing if pause_resume.get() == 'Pause': pygame.mixer.music.pause() pause_resume.set('Resume') elif pause_resume.get() == 'Resume': pygame.mixer.music.unpause() pause_resume.set('Pause') |
五、关闭
先结束现成，然后关闭窗体。

七、改进
下一步，可加入播放列表，点选播放音乐，也可以拖动进度播放。
以上就是基于Python实现音乐播放器的实现示例代码的详细内容，更多关于Python音乐播放器的资料请关注服务器之家其它相关文章！
