It doesn't have to be a flat record. You can write a custom a Handler that does anything you want with the LogRecord, e.g. writing structured data to a relational database. With logging filters, you could set that up either in addition to or in place of the standard flatfile logging. > I want to be able to insert commands inside of the loops that log > certain variable states, completed stages of the algorithm (assume > it's hierarchical), text warnings, and possibly even 'pointers' to > graphical output objects of some of the intermediate data (e.g. > matplotlib object handles for lines, points).

You could potentially use that to define whatever sort of categorization you want. -- https://mail.python.org/mailman/listinfo/python-list
