If you're not used to work with the standard module logging, this snippet will allow you to incorporate a logger in your application without effort. It gives you a starting point before you try to use more sophisticated features of the logging module.

#!/usr/bin/env python
Module simplelog :

provides immediate logging to a text file (using module logging)


from simplelog import *
log = getSimpleLogger("myPath/myFile.txt")
log.info("an example message")


getSimpleLogger can be called multiple times with the same
filename. It identifies the logger with the file's basename,
so you can't have 2 different loggers named myFile.txt (even
in different folders.)

import logging 
import os .path 
__all__ =["getSimpleLogger"]
_loggers ={}

def getSimpleLogger (pathToFile ):
  "returns a logger to the given file"
  name =os .path .basename (pathToFile )
  theLogger =logging .getLogger (name )
  if name in _loggers :
    return theLogger 
  _loggers [name ]=True 
  theLogger .setLevel (logging .DEBUG )
  theHandler =logging .FileHandler (pathToFile ,'w')
  theFormatter =logging .Formatter (
  "%(asctime)s %(levelname)-8s %(message)s",
#"%a, %d %b %Y %H:%M:%S",
  theHandler .setFormatter (theFormatter )
  theLogger .addHandler (theHandler )
  return theLogger 

if __name__ =="__main__":
  logger =getSimpleLogger ("foo.txt")
  for i in range (20 ):
    logger .info ("current index is %d"%i )
