Python做一个简易的音乐播放器
简易音乐播放器
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()
运行效果：
开始搭建音乐播放器
首先了解项目知识点和所需模块
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 3.7
先看一下运行效果：
代码讲解：
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('460x500+500+100')
root.resizable(False,False) # 不能拉伸
# 创建一个 ttk 样式
style = ttk.Style()
# 设置框架的背景颜色
# style.configure("TFrame", background="#98F5F9")
# 设置前景颜色和边框颜色
style.configure("TFrame", background="#98F5F9", foreground="#000000", bordercolor="#000000")
frame = ttk.Frame(root, width=460, height=500)
frame.pack()
# 显示
root.mainloop()
按钮
# 添加按钮
buttonChoose = tkinter.Button(root,text='添加',command=buttonChooseClick,fg="#000000",bg="#EFCDF8")
# 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,command=buttonPlayClick,fg="#000000",bg="#B2F199")
buttonPlay.place(x=120,y=10,width=50,height=20)
buttonPlay['state'] = 'disabled'
# 停止按钮
buttonStop = tkinter.Button(root, text='停止',command=buttonStopClick,fg="#000000",bg="#F8B6B6")
buttonStop.place(x=190, y=10, width=50, height=20)
buttonStop['state'] = 'disabled'
# 下一首
buttonNext = tkinter.Button(root, text='下一首',command=buttonNextClick,fg="#000000",bg="#F6E3C4")
buttonNext.place(x=260, y=10, width=50, height=20)
buttonNext['state'] = 'disabled'
# 上一首
buttonPrev = tkinter.Button(root, text='上一首',command=buttonPrevClick,fg="#000000",bg="#F6E3C4")
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=50, y=30, width=330, 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,command=control_voice)
s.place(x=50, y=50, width=330) 
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 len(res):
pygame.mixer.init()
global num
while playing:
if not pygame.mixer.music.get_busy():
netxMusic = res[num]
print(netxMusic)
print(num)
pygame.mixer.music.load(netxMusic.encode())
# 播放
pygame.mixer.music.play(1)
if len(res) -1 == num:
num = 0
else:
num = num + 1
netxMusic = netxMusic.split('\\')[1:]
musicName.set('playing......' + ''.join(netxMusic))
else:
time.sleep(0.1)
# 点击播放
def buttonPlayClick():
buttonNext['state'] = 'normal'
buttonPrev['state'] = 'normal'
# 选择要播放的音乐文件夹
if pause_resume.get() == '播放':
pause_resume.set('暂停')
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()
elif pause_resume.get() == '暂停':
# pygame.mixer.init()
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 = 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
