如何将调试级别记录到文件，但仅在python屏幕上记录信息级别

Question

in my python project i have several lines that are logging with debug level and other with info level. Now, when i run my code i can set at the begging the log level to info or debug level and that will log to a file and on the screen only the info or both info/debug messages accordingly.

How can i achieve to set to log to file always debug level but on screen always info level?

Example (only a small part):

loggername = 'Main.Case.'
self.logger = logging.getLogger(loggername)
self.logger.info('case() - Started')
self.logger.debug('System ready...')
self.logger.debug('File ready...')
self.logger.debug('Memory ready...')
self.logger.info('case() - Ready')

This would print with info level only (on screen and log file):

Main.Case.case() - Started
Main.Case.case() - Ready

With debug level i will get (on screen and log file):

Main.Case.case() - Started
Main.Case.System ready...
Main.Case.File ready...
Main.Case.Memory ready...
Main.Case.case() - Ready

I actually would like to have on screen always only the info level lines and in the log file info/debug level!

When i activate debug level then i will get everything to both out puts (screen/file).

Any one any idea??

Thanks in adv.
