Yes, that's why you get duplicated lines in the log. > What would be a better way to handle this? I'm not sure why you need all the code you've posted. The logging package allows you to add tracebacks to your logs by using the exception() method, which logs an ERROR with a traceback and is specifically intended for use from within exception handlers. All that stuff with temporary files seems completely unnecessary, even with Python 2.3. In general, avoid adding handlers more than once - which you are almost guaranteed to not avoid if you do this kind of processing in a constructor. If you write your applications without using the exceptionLogger class (not really needed, since logging exceptions with tracebacks is part and parcel of the logging package's functionality since its introduction with Python 2.3), what functionality do you lose?
