一、环境设置
二、播放功能
三、停止功能
四、暂停与恢复
五、关闭
六、完整代码
七、改进
一、环境设置第一步引入必须的各类包
import os
import tkinter
import tkinter.filedialog
import random
import time
import threading
import 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。
# 关闭程序时执行的代码
def closeWindow():
# 修改变量，结束线程中的循环
global playing
playing = False
time.sleep(0.3)
try:
# 停止播放，如果已停止，
# 再次停止时会抛出异常，所以放在异常处理结构中
pygame.mixer.music.stop()
pygame.mixer.quit()
except:
pass
root.destroy()

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易知道(ezd.cc)其它相关文章！
