How I built a CLI music player in Python and what I learned

说明与用途

使用Python构建的CLI音乐播放器，集成Deezer API、yt-dlp、VLC和SQLite。展示了API集成、流式播放以及数据库锁定问题的处理。

问题

Build a daily-use command line music player that integrates with Deezer, streams audio, and manages playlists locally.

结果

A functional CLI music player with integrated search, streaming, playback, and local data storage, plus lessons on database locking and environment debugging.

工作流

• 1. Use Deezer API to search artists and songs.
• 2. Fetch and stream audio with yt-dlp.
• 3. Control playback using VLC.
• 4. Store playlists and favorite artists in a local SQLite database.
• 5. Handle API calls with requests.
• 6. Resolve database locking by ensuring all connections are closed and committing after both inserts.

证据

When I added the feature to save artists and songs simultaneously, I kept getting a "database locked" error.

Killed the processes, added proper connection closing on exit, fixed immediately.
