Question

I have a django list as below: the hotess1 is a database result set.

for hotel in hotels1:
            if models.CalendarDay.objects.filter(hotel=hotel, date=date).count() == 0:
                similar_venues.append(hotel)

The list size is dynamic but i want to return only first three values

I can do as below:

for hotel in hotels:
        if models.CalendarDay.objects.filter(hotel=hotel, date=date).count() == 0:
            similar_venues.append(hotel)
            counter += 1
            if counter == 3: break

but i want to do it in a better way.. any help

Answer 1

You can use the slice operator: my_list[:3] will return a list containg the first three values of my_list.

(unless there are less than three values, in which case you get everything back).
