structlog makes logging in Python faster, less painful, and more powerful by adding structure to your log entries. It has been successfully used in production at every scale since 2013, while embracing cutting-edge technologies like asyncio or type hints along the way, and influenced the design of structured logging packages in other ecosystems.

Thanks to its highly flexible design, 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.

structlog comes with support for JSON, logfmt, as well as pretty console output out-of-the-box:
