Sometimes you’re in a situation where you need to debug something that is inside a piece of code like this:
try: [...] except Exception as e: [...] An option would be printing e but it will show only the exception message, instead of the traceback. You can solve this by adding:
import traceback try: [...] except Exception as e: [...] print(''.join(traceback.format_exception(None, e, e.__traceback__))) It will show the exception and the traceback.

I joined iib in January and since the beginning it was clear that I’d have a lot of fun automating a few manual process. The development team is formed by three persons: the CTO, another developer and me. The team is small but step by step we’re going towards the technical excellence we want. :)

For her, backups aren’t a trivial task, so I decided to help her on this quest. I had an idea: building a WhatsApp bot to backup her pictures to my Dropbox.

Sometimes we need to link tasks according to the outcomes, similar to an if/else flow. With Celery is possible to do it using link and link_error.
To give you an idea, let’s say that we need to send an important SMS to our customer. If this succeed, we should sync this SMS to our CRM tool; if something went wrong, we should contact IT right away.
We can do it by linking our send_sms task to other tasks.
