structlog makes structured logging with incremental context building and arbitrary formatting as easy as:
>>> from structlog import get_logger
>>> log = get_logger()
>>> log = log.bind(user='anonymous', some_key=23)
>>> log = log.bind(user='hynek', another_key=42)
>>> log.info('user.logged_in', happy=True)
some_key=23 user='hynek' another_key=42 happy=True event='user.logged_in'
Please note that this example does not use standard library logging (but could so easily). The logger that’s returned by get_logger() is freely configurable and uses a simple PrintLogger by default.

Since structlog avoids monkey-patching and events are fully free-form, you can start using it today!
structlog can be used immediately with any existing logger. However it comes with special wrappers for the Python standard library and Twisted that are optimized for their respective underlying loggers and contain less magic.
