實戰項目 —python實現本地音樂播放器

4 人贊了文章

隨著網路的發展，我們已經很少將音樂下載到本地，而是直接在線聽歌，方便而又直接。也許你用的音樂播放器是這個

也許是這個

這都不是重點，今天我們要用python自己打造一款音樂播放器。

使用python製作一個本地的音樂播放器，通過tkinter庫編寫音樂播放器的界面，使用eyeD3庫來處理MP3文件，獲取歌曲的時長。打開本地音頻文件添加到歌曲列表，然後有播放、停止和暫停功能，還可以選擇上一曲和下一曲，可以通過滑塊進行音量控制。

模塊準備

安裝tkinter模塊

安裝eyeD3模塊

注意：在安裝eyeD3時，可用pip進行安裝，如果在import時出現報錯ImportError: failed to find libmagic. Check your installation。解決辦法是安裝python_magic_bin，python_magic_bin可在網站https://pypi.org/project/python-magic-bin/0.4.14/上下載whl文件，然後直接pip安裝即可。

完整代碼如下
