這篇文章主要介紹了如何利用Python編寫簡易的音樂播放器，文中的示例代碼講解詳細，具有一的參考價值，需要的小伙伴可以參考一下

一、環(huán)境設(shè)置

第一步引入必須的各類包

import os
import tkinter
import tkinter.filedialog
import random
import time
import threading
import pygame

特別是pygame需要手動安裝

pip install pygame

二、播放功能

首先選擇音樂目錄，然后創(chuàng)建播放現(xiàn)成，播放音樂。

# 播放按鈕
def buttonPlayClick():
    # 選擇要播放的音樂文件夾
    global folder
    if not folder:
        folder = tkinter.filedialog.askdirectory()
    if not folder:
        return

    global playing
    playing = True
    # 創(chuàng)建一個線程來播放音樂，當(dāng)前主線程用來接收用戶操作
    t = threading.Thread(target=play)
    t.start()

    # 根據(jù)情況禁用和啟用相應(yīng)的按鈕
    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，當(dāng)然更改按鈕狀態(tài)也屬常規(guī)操作。

def buttonStopClick():
    global playing
    playing = False

    pygame.mixer.music.stop()
    musicName.set('暫時沒有播放音樂')

    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、暫停與恢復(fù)

這個好理解，也是直接現(xiàn)成操作，加個判斷，狀態(tài)更改。

# 暫停與恢復(fù)，兩個功能共用一個按鈕
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、關(guān)閉

先結(jié)束現(xiàn)成，然后關(guān)閉窗體。

# 關(guān)閉程序時執(zhí)行的代碼
def closeWindow():
    # 修改變量，結(jié)束線程中的循環(huán)
    global playing
    playing = False
    time.sleep(0.3)

    try:
        # 停止播放，如果已停止，
        # 再次停止時會拋出異常，所以放在異常處理結(jié)構(gòu)中
        pygame.mixer.music.stop()
        pygame.mixer.quit()
    except:
        pass
    root.destroy()
