logging module example

[Chris Smith]

 One thing that made little sense to me when I was first working on
this is the following variation on the original script:

#--begin test script--
import logging

forest      = ["root","trunk","branch","leaf"]
lumber_jack = {forest[0] : logging.DEBUG
              ,forest[1] : logging.INFO
              ,forest[2] : logging.WARNING
              ,forest[3] : logging.ERROR  }
log_name    = []
for log in forest:
    mounty  = logging.FileHandler("%s%s.txt" % ("/home/smitty/mddl/",log))
    log_name.append(log)
    print "Instantiating %s"  % ".".join(log_name)
    timber  = logging.getLogger(".".join(log_name))

    #Comment out explit setting of level for logger
    #timber.setLevel(lumber_jack[log])

    #Commented out totally, called without argument, or called with
    # logging.NOTSET all produce same output

    #timber.setLevel(logging.NOTSET)
    timber.addHandler(mounty)
    if   lumber_jack[log] == logging.DEBUG:
        timber.debug(  "%s's a lumberjack, and he's OK." % log)
    elif lumber_jack[log] == logging.INFO:
        timber.info(   "%s's a lumberjack, and he's OK." % log)
    elif lumber_jack[log] == logging.WARNING:
        timber.warning("%s's a lumberjack, and he's OK." % log)
    elif lumber_jack[log] == logging.ERROR:
        timber.error(  "%s's a lumberjack, and he's OK." % log)
    mounty.emit( logging.LogRecord( timber
                                  , 0
                                  , "/mnt/dmz/proj/mddl4/mddl.py"
                                  , 37
                                  , "burp?"
                                  , None
                                  , None   ))
#--end test script--

#expected output

$ cat root.txt
root's a lumberjack, and he's OK.
burp?
trunk's a lumberjack, and he's OK.
branch's a lumberjack, and he's OK.
leaf's a lumberjack, and he's OK.
$ cat trunk.txt
trunk's a lumberjack, and he's OK.
burp?
branch's a lumberjack, and he's OK.
leaf's a lumberjack, and he's OK.
$ cat branch.txt
branch's a lumberjack, and he's OK.
burp?
leaf's a lumberjack, and he's OK.
$ cat leaf.txt
leaf's a lumberjack, and he's OK.
burp?

#actual output

$ cat root.txt
burp?
branch's a lumberjack, and he's OK.
leaf's a lumberjack, and he's OK.
$ cat trunk.txt
burp?
branch's a lumberjack, and he's OK.
leaf's a lumberjack, and he's OK.
$ cat branch.txt
branch's a lumberjack, and he's OK.
burp?
leaf's a lumberjack, and he's OK.
$ cat leaf.txt
leaf's a lumberjack, and he's OK.
burp?

 At any rate, I see now that I want to use logging.setLevel() to lay
in my own, more descriptive, levels, and then the straight
logging.log() function to do that for me.
 Ah, the learning curve.
Best,
Chris
