Python has a standard logging module modeled after Apache log4j - the standard logging system for Java. Here we gather additional information about logging in Python in general that is missing from the docs.
LoggingPackage page contains discussions about logging module features.
http://sourceforge.net/projects/log4py/ is another log4j port to Python (not sure how far it is from standard package - anybody want to explore and post results here?)
http://packages.python.org/Logbook/ replacement for the standard library’s logging module.
