Are you sure that is what you want? It seems very complicated unless you
are allowing the user to supply an abbreviated form. Otherwise
if logleveltocheck.upper() in ['DEBUG', 'INFO', 'WARNING',
'ERROR', 'CRITICAL']:
return logleveltocheck.upper()
might be easier?

I'm not sure what this is supposed to be doing!
------ end ----
I am thinking about a module where user can change the logging mode and
doing so without modifying code, I am thinking to extend it with parameter
module.
I seen many software that if user set logging Level 1,2,3,4 or support
mode, then application will create more information in the log file
accordingly. The method I am using most likely is wrong. I dont know where
should I trigger the log Level to achieve parameterize logging mode.
I have one question I have following set
stream_handler.setLevel('INFO') <--- handler to console
file_handler.setLevel('INFO') <---- handler to file
both are added to logger
logger.addHandler(file_handler)
logger.addHandler(stream_handler)
If I did not set the logger.setLevel like following
logger.setLevel('INFO')
the logger unable to process
logger.info('Current log level is : {}'.format(logger.level))
----> return 10 if logger.setLevel('DEBUG') if not
My question is what is the different between
stream_handler.setLevel('INFO')
and
logger.setLevel('INFO')
Why do we need
logger.setLevel('INFO')
if we stated following
stream_handler.setLevel('INFO') <--- handler to console
file_handler.setLevel('INFO') <---- handler to file
--- complete code

#DEBUG : Detailed information, typically of interest only when
diagnosing problems.
#INFO : Confirmation that things are working as expected.
#WARNING (default): An indication that something unexpected happened, or
indicative of some problem in the near future
# (e.g. 'disk space low'). The software is still working as
expected.
#ERROR : Due to a more serious problem, the software has not been able
to perform some function.
#CRITICAL :A serious error, indicating that the program itself may be
unable to continue running.
