python exception message capturing


You have to define which type of exception you want to catch. So write except Exception, e: instead of except, e: for a general exception (that will be logged anyway).

Other possibility is to write your whole try/except code this way:

try:    with open(filepath,'rb') as f:        con.storbinary('STOR '+ filepath, f)    logger.info('File successfully uploaded to '+ FTPADDR)except Exception, e: # work on python 2.x    logger.error('Failed to upload to ftp: '+ str(e))

in Python 3.x and modern versions of Python 2.x use except Exception as e instead of except Exception, e:

try:    with open(filepath,'rb') as f:        con.storbinary('STOR '+ filepath, f)    logger.info('File successfully uploaded to '+ FTPADDR)except Exception as e: # work on python 3.x    logger.error('Failed to upload to ftp: '+ str(e))


The syntax is no longer supported in python 3. Use the following instead.

try:    do_something()except BaseException as e:    logger.error('Failed to do something: ' + str(e))


Updating this to something simpler for logger (works for both python 2 and 3). You do not need traceback module.

import logginglogger = logging.Logger('catch_all')def catchEverythingInLog():    try:        ... do something ...    except Exception as e:        logger.error(e, exc_info=True)        ... exception handling ...

This is now the old way (though still works):

import sys, tracebackdef catchEverything():    try:        ... some operation(s) ...    except:        exc_type, exc_value, exc_traceback = sys.exc_info()        ... exception handling ...

exc_value is the error message.
