This will catch *every* exception, and throw it away before it gets to
your "print" statement.

This is almost never a good idea. You should catch *specific*
exceptions that you know you can deal with at that point in the code.

    import logging
    try:
        foo = 12 / 0
    except ZeroDivisionError, e:
        print "You *knew* this was going to happen: '%s'" % e
        logging.error(str(e))

This allows all other exceptions to propogate back through the call
stack.
