Python - Logging and levels

Question

I use python module logging to generate log files and console print. I set up my script to log all errors levels, without DEBUG to file. But i have trouble with set up handler for console printing. On console i want to display level INFO and below, not up like setLevel doing. Is any way to do this with inline code?

stackoverflow.com/questions/1383254/… might be help full.

I'm not sure exactly what you mean by "inline code", but you can achieve this using Filters.

class InfoAndLower(logging.Filter):
    def filter(self, record):
        return record.levelno <= logging.INFO

and then attach a filter instance to your console handler.

h = logging.StreamHandler(sys.stdout)
h.addFilter(InfoAndLower())

In Python 3.2 and later, you don't need to create a class - a callable will do:

h.addFilter(lambda record: record.levelno <= logging.INFO)
