Good, you've found the table of predefined logging levels in the module 
docs then?

You'll notice that they are spaced apart by 10; in principle one can 
choose levels between them. Kind of irrelevant if nothing logs at such 
an intermediate level, but...

For example, I define for myself a TRACE value between INFO and WARNING, 
and a trace() call which logs at that level (like the predefined 
warning() function logs at logging.WARNING level). I often find my info 
calls are too verbose, and the warnings are only for badness, so I have 
a kind of intermediate call for "high level" far less frequent logs.
