structlog makes structured logging in Python easy by augmenting your existing logger. It allows you to split your log entries up into key/value pairs and build them incrementally without annoying boilerplate code.

It's dual-licensed under Apache License, version 2 and MIT, available from PyPI, the source code can be found on GitHub, the documentation at http://www.structlog.org/.

structlog targets Python 2.6, 2.7, 3.3, 3.4, and PyPy with no additional dependencies for core functionality.
