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()

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

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

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')

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

        # 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 = threading.Thread(target=play)
    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 = len(res) - 2
        # 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:
        pass
    root.destroy()
