Python實現(xiàn)多功能音樂播放器詳解

 更新時間：2022年02月16日 09:31:40   作者：松鼠愛吃餅干  
這篇文章主要介紹了如何通過Python制作一個簡易的音樂播放器，文中的示例代碼講解詳細(xì)，對我們學(xué)習(xí)或工作有一定價值，需要的可以參考一下

前言

就是用Python做一個簡易的音樂播放器，廢話不多說，咱們直接開干

當(dāng)然，今天做這個肯定不是最簡單的，最簡單的音樂播放器，9行代碼足以

import time
import pygame

file = r'歌曲路徑'
pygame.mixer.init()
print('正在播放',file)
track = pygame.mixer.music.load(file)
pygame.mixer.music.play()
time.sleep(130)
pygame.mixer.music.stop()

準(zhǔn)備工作

知識點和所需模塊

1.python基礎(chǔ)知識

2.requests庫

3.time

4.pygame

5.tkinter

6.線程

環(huán)境

windows

pycharm 2021.2

python 3.8

效果展示

簡易版的

還有個半成品的，目前代碼沒寫完

導(dǎo)入模塊

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

界面

root = tkinter.Tk()
root.title('音樂播放器')
root.geometry('460x600+500+100')

按鈕

# 添加按鈕

功能

創(chuàng)建一個文件目錄

folder =''
res = []
num = 0
now_music = ''

音樂讀取功能

def buttonChooseClick():
    global folder
    global res
    if not folder:
        folder = tkinter.filedialog.askdirectory()
        musics = [folder + '\\' + music
                  for music in os.listdir(folder) \
\
                  if music.endswith(('.mp3','.wav','.ogg'))]
        ret = []
        for i in musics:
            ret.append(i.split('\\')[1:])
            res.append(i.replace('\\','/'))

    if not folder:
        return

    global playing
    playing = True
    # 根據(jù)情況禁用和啟用相應(yīng)的按鈕
    buttonPlay['state'] = 'normal'
    buttonStop['state'] = 'normal'
    # buttonPause['state'] = 'normal'
    pause_resume.set('播放')

顯示已加載的音樂

var2 = tkinter.StringVar()
var2.set(ret)
lb = tkinter.Listbox(root,listvariable=var2)
lb.place(x=50,y=100,width=260,height=300)

        # pygame.mixer.init()
        pygame.mixer.music.unpause()

        pause_resume.set('暫停')

停止播放

def buttonStopClick():
    global playing
    playing = False
    pygame.mixer.music.stop()

下一首

def buttonNextClick():
    global playing
    playing = False

    global num
    if len(res) == num:
        num = 0

    playing = True
    # 創(chuàng)建線程播放音樂,主線程用來接收用戶操作

上一首

def buttonPrevClick():
    global playing
    playing = False

    #
    # pygame.mixer.quit()
    global num

    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()

音量控制

def control_voice(value=0.5):
    pygame.mixer.music.set_volume(float(value))

關(guān)閉窗口

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:
