百木园前言
就是用Python做一个简易的音乐播放器，废话不多说，咱们直接开干 当然，今天做这个肯定不是最简单的，最简单的音乐播放器，9行代码足以
import time
import pygame
file = r'歌曲路径'
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()
开始今天的代码之前，准备工作
知识点和所需模块
1.python基础知识 2.requests库 3.time 4.pygame 5.tkinter 6.线程
环境
- windows
- pycharm 2021.2
- python 3.8
完整代码，运行即可，记得👍👍👍（直接明示了）

效果展示
简易版的
还有个半成品的，目前代码没写完
导入模块
import os
import time
import tkinter
import tkinter.filedialog
import threading
import pygame
一、界面
root = tkinter.Tk()
root.title('音乐播放器')
root.geometry('460x600+500+100')
root.resizable(False,False) # 不能拉伸
# 显示
root.mainloop()
按钮
# 添加按钮
buttonChoose = tkinter.Button(root,text='添加')
# 布局
buttonChoose.place(x=50,y=10,width=50,height=20)
# 播放按钮
pause_resume = tkinter.StringVar(root,value='播放')
buttonPlay = tkinter.Button(root,textvariable=pause_resume)
buttonPlay.place(x=190,y=10,width=50,height=20)
buttonPlay['state'] = 'disabled'
# 停止按钮
buttonStop = tkinter.Button(root, text='停止')
buttonStop.place(x=120, y=10, width=50, height=20)
buttonStop['state'] = 'disabled'
# 下一首
buttonNext = tkinter.Button(root, text='下一首')
buttonNext.place(x=260, y=10, width=50, height=20)
buttonNext['state'] = 'disabled'
# 上一首
buttonPrev = tkinter.Button(root, text='上一首')
buttonPrev.place(x=330, y=10, width=50, height=20)
buttonPrev['state'] = 'disabled'
# 标签
musicName = tkinter.StringVar(root, value='暂时没有播放音乐...')
labelName = tkinter.Label(root, textvariable=musicName)
labelName.place(x=10, y=30, width=260, height=20)
# 音量控制
# HORIZONTAL表示为水平放置，默认为竖直,竖直为vertical
s = tkinter.Scale(root, label='音量', from_=0, to=1, orient=tkinter.HORIZONTAL,
length=240, showvalue=0, tickinterval=2, resolution=0.1)
s.place(x=50, y=50, width=200)
二、功能
创建一个文件目录
folder =''
res = []
num = 0
now_music = ''
音乐读取功能
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
# 根据情况禁用和启用相应的按钮
buttonPlay['state'] = 'normal'
buttonStop['state'] = 'normal'
# buttonPause['state'] = 'normal'
pause_resume.set('播放')
显示已加载的音乐
var2 = tkinter.StringVar()
var2.set(ret)
lb = tkinter.Listbox(root,listvariable=var2)
lb.place(x=50,y=100,width=260,height=300)
播放音乐
def play():

if not folder:
return
global playing

pygame.mixer.music.pause()
pause_resume.set('继续')
elif pause_resume.get() == '继续':
# pygame.mixer.init()
pygame.mixer.music.unpause()
pause_resume.set('暂停')
停止播放
def buttonStopClick():
global playing
playing = False
pygame.mixer.music.stop()
下一首
def buttonNextClick():
global playing
playing = False
pygame.mixer.music.stop()
global num
if len(res) == num:
num = 0
playing = True
# 创建线程播放音乐,主线程用来接收用户操作

t.start()
上一首
def buttonPrevClick():
global playing
playing = False
pygame.mixer.music.stop()
#
# pygame.mixer.quit()
global num
# num += 1
# num -= 1
if num == 0:

# num -= 1
elif num == len(res) - 1:
num -= 2
else:
num -= 2
# num -= 1
print(num)
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()
音量控制
def control_voice(value=0.5):
pygame.mixer.music.set_volume(float(value))
关闭窗口
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:
