Python list comprehension Remove duplicates

Question

I want unique elements in hubcode_list. I can do it by

hubcode_alarm_obj = HubAlarm.objects.all()
for obj in hubcode_alarm_obj:
    hubcode = obj.h         


        

Answer 1

Since you are using django, let the database do the filtering for you. It will be (by far) the fastest option:

objects = HubAlarm.objects.exclude(hubcode__in=hubcode_list)

See the documentation for more.
