print_field = 'name'

for item in grade_list:
    print item.(  print_field...  )

result ->

john
cavin

Q) fill in the blank please. Is it possible?

Answer 1

Yes you can do this with the getattr built-in function.

grade_list = AAA.objects.all()
print_field = 'name'

for item in grade_list:
    print getattr(item, print_field)
