Python Logging That Actually Helps

Logging is the narrative of your system. Make it concise, contextual, and consistent.

1. Start with intent

Every log entry should answer a question. Is it for debugging, auditing, or user-facing support?

2. Structure your logs

Use JSON or key-value formats. Plain text is a dead end for automated analysis.

3. Log context, not just events

Include request IDs, pipeline stage names, and data volume summaries.

4. Keep levels meaningful

If everything is a warning, nothing is. Tune log levels and aggregate noise.
