Structured Logging for Python¶
Release v21.1.0 (What's new?).
structlog
makes logging in Python faster, less painful, and more powerful by adding structure to your log entries.
It’s up to you whether you want structlog
to take care about the output of your log entries or whether you prefer to forward them to an existing logging system like the standard library’s logging
module.
