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!
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
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)
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'
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')
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()
