When we run

, and then
logging.error( "Test01\n" )
logging.debug("Test02\n")
logging.info("Test03\n")
logging.error( "Test04\n" )
, only the error log lines get sent to the file.
How do I get info() and debug() to go to the file, as well?
You do this by adjusting the logging level of your programme. The idea
is that you can put logging calls all through your code at suitable
levels (info, error, warning debug) and change the logging verbosity
just by adjusting the logging level of the logger involved.
So I often have a sniff around at startup in my programmes where I set
up the logging, and default to logging.WARNING unless stderr is a
terminal (inferring "interactive") and use logging.INFO. A command line
switch or environment variable might be used to override these defaults.
Having picked a level:
root_logger = logging.getLogger()
root_logger.setLevel(level)
sets the level of the root logger, thus changing the verbosity.
Obviously adjust if you've got a special purpose logger rather than the
root logger.
