Cron should send mail with the output of the command in the crontab. Because the grid crontab runs jsub, and not your command directly, the only mail you will get from cron is when your job has been submitted. You can use the -m option on jsub to send mail in a few different cases (see https://wikitech.wikimedia.org/wiki/Help:Toolforge/Grid#jsub_options). jsub -m a ... should send mail when the job is aborted, but won't include any more information. You can also send mail directly from your code, https://wikitech.wikimedia.org/wiki/Help:Toolforge/Email has some more information. Many logging frameworks, including `logging` in Python, support sending log messages over SMTP.
