Python實現多功能音樂播放器詳解

2022-02-16 10:00:24

前言

就是用Python做一個簡易的音樂播放器，廢話不多說，咱們直接開幹

當然，今天做這個肯定不是最簡單的，最簡單的音樂播放器，9行程式碼足以

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()

準備工作

知識點和所需模組

1.python基礎知識

2.requests庫

3.time

4.pygame

5.tkinter

6.執行緒

環境

windows

pycharm 2021.2

python 3.8

效果展示

簡易版的

還有個半成品的，目前程式碼沒寫完

匯入模組

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

介面

root = tkinter.Tk()
root.title('音樂播放器')
root.geometry('460x600+500+100')
root.resizable(False,False)  # 不能拉伸

# 顯示
root.mainloop()

按鈕

# 新增按鈕
buttonChoose = tkinter.Button(root,text='新增')
# 佈局
buttonChoose.place(x=50,y=10,width=50,height=20)

# 播放按鈕
pause_resume = tkinter.StringVar(root,value='播放')
buttonPlay = tkinter.Button(root,textvariable=pause_resume)

s.place(x=50, y=50, width=200)

功能

建立一個檔案目錄

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
    # 根據情況禁用和啟用相應的按鈕
    buttonPlay['state'] = 'normal'
    buttonStop['state'] = 'normal'
    # buttonPause['state'] = 'normal'
    pause_resume.set('播放')

顯示已載入的音樂

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

播放音樂

                netxMusic = netxMusic.split('\')[1:]
                musicName.set('playing......' + ''.join(netxMusic))
            else:
                time.sleep(0.1)

        # 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
    pygame.mixer.music.stop()
    global num
    if len(res) == num:
        num = 0

    playing = True
    # 建立執行緒播放音樂,主執行緒用來接收使用者操作
    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
    # 建立一個執行緒來播放音樂，當前主執行緒用來接收使用者操作
    t = threading.Thread(target=play)
    t.start()

音量控制

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

關閉視窗

def closeWindow():
    # 修改變數，結束執行緒中的迴圈
    global playing
    playing = False
    time.sleep(0.3)

    try:
        # 停止播放，如果已停止，
        # 再次停止時會丟擲異常，所以放在例外處理結構中
        pygame.mixer.music.stop()
        pygame.mixer.quit()

    except:
        pass
    root.destroy()
