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

Описание и применение

CLI‑музыкальный проигрыватель на Python, использующий Deezer API, yt-dlp и VLC, с локальной базой SQLite. Решена проблема блокировки БД, получена практическая работа с API и потоковым воспроизведением.

Задача

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

Результат

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

Рабочий процесс

• 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.

Доказательства

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.
