If you know of any, can you point me to them?

There's also the issue of how to direct logging -- does every module have its own logger object, or every class, or does every *instance* of a class that may do something loggable have its own logger? Either way, the logging becomes a new, explicit part of the API to which the application (or the library calling it) should have access. And yes, such APIs would have a lot of overhead. I suspect that the libraries you referred to that wrap calls you wanted to be logged have the same attitude: logging is up to the application. I have worked extensively with large code bases that did a considerate amount of logging, and I've never felt the need (not heard others express it) to have logging in the stdlib. > > It's not logging per se, but the standard library does have an > > extensive and growing list of audit events that are intended to assist > > with testing, logging and security monitoring. > > Thanks, It looks like an audit hook could work. > But understand that these are meant for a totally different purpose. -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-change-the-world/>
