Getting Started with Claude Code

You're a developer who just joined a new team working on a music analytics platform. Your colleague mentioned that Claude Code can help you understand unfamiliar codebases quickly.

Your project directory contains analytics.py with this function:

def calculate_album_stats(albums, min_tracks=5, multiplier=1.2):
    """Process album data and return statistics for qualifying albums."""
    output = []
    for album in albums:
        track_count = album.get('track_count', 0)
        if track_count > min_tracks:
            adjusted_popularity = album.get('popularity', 0) * multiplier
            tier = 'platinum' if adjusted_popularity > 80 else 'gold'
            output.append({
                'album_id': album['album_id'],
                'title': album['title'],
                'original_popularity': album.get('popularity', 0),
                'adjusted_popularity': adjusted_popularity,
                'tier': tier
            })
    return sorted(output, key=lambda x: x['adjusted_popularity'], reverse=True)[:5]
