基于Python怎么实现音乐播放器

本篇内容主要讲解"基于Python怎么实现音乐播放器"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"基于Python怎么实现音乐播放器"吧!

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。

# 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()
