<QuerySet [{'course_code': 11}]>

Answer 1

course_qs = <whatever query gave you the queryset>
for course in course_qs:
    print(course['course_code'])

Answer 2

courses = <your query set>
print(courses[0]['course_code'])

用这个

someTable.objects.all()[0]['course_code']

或者

someTable.objects.values_list('course_code', flat = True)
