How can I retry failed tasks in Celery?

You can use the retry method in your task definition to retry failed tasks. Would you like an example?

Yes, please provide an example of how to implement that.

Sure! Here's a simple example:

from celery import Celery

app = Celery('tasks', broker='redis://localhost:6379/0')

@app.task(bind=True, max_retries=3)
def my_task(self):
    try:
        # Your task logic here
        pass
    except Exception as exc:
        raise self.retry(exc=exc)

What happens if all retries fail?

If all retries fail, the task will be marked as failed, and you can handle it using the on_failure method to log or notify.
