[Django]-Extract values from Django in Python 3

Why not a simple list comprehension?

qs = UnitTestCollection.objects.filter(unit__type=unit_type)
my_values = [item.field_name for item in qs]

Or use values_list() to just fetch the specific field for each item directly in your queryset, with the advantage of lazy evaluation:

qs = UnitTestCollection.objects.filter(unit__type=unit_type)\
                               .values_list('field_name', flat=True)

values_list is better than a list comprehension because querysets are lazily evaluated. They won’t be executed until you actually need them.

queryset = UnitTestCollection.objects.filter(unit__type=unit_type).values_list('<insert field>', flat=True)

This will return [field1, field2, field3...]

if you use .values('<insert field>') you’ll get [{field: field value1}, {field: field value2}, {field: field value3}...]
