I am downloading a file from the net, and it fails even though I am doing:

for p in query:try:except IOError as e:print e;

If there is an error, I want to log it, and then continue on with the next file.

In this loop, I am trying to download an image, if for some reason the filename was bad, or the website was down, etc., I want to continue with the next item in the for loop.

Is there a more generic error that won't fail and continue processing?

Also, how can I log errors to a file?

You could use the logging module:

import logging
logging.basicConfig(filename='/tmp/myapp.log', level=logging.DEBUG, format='%(asctime)s %(levelname)s %(name)s %(message)s')
logger=logging.getLogger(__name__)try:1/0
except ZeroDivisionError as err:logger.error(err)

Running the script writes in /tmp/myapp.log:

% cat /tmp/myapp.log
