I'm working on a python assignment and I have no idea where to start on this function:Consumes a list of Submission dictionaries and prints out the group name and unweighted grade for each group. The unweighted grade is the total score for the group's submissions divided by the total points_possible for the group's submissions, multiplied by 100 and rounded. Like the summarize_points function, you should ignore the submission without a score (i. e. the submission's score is None). You are recommended to apply the Dictionary Summing Pattern to implement this function. Sample Output:* Class Activities : 78* Discussion Forums : 80* Learning Quizzes : 88* Programming Problems : 83First entry of dictionary (out of 100):[{'assignment': {'assignment_group_id': 82390,'due_at': '2017-08-30T16:20:00Z','group': {'group_weight': 25,'id': 82390,'name': 'Learning Quizzes','rules': {}},'id': 270567,'lock_at': '2017-10-01T00:00:00Z','name': '#1.2) Quiz: Introduction','points_possible': 10.0,'unlock_at': '2017-08-27T16:40:00Z'},'assignment _id': 270567,'attempt': 3,'excused': False,'graded_at': '2017-09-12T13:04:04Z','grader_id': 10926,'late': False,'missing': False,'score': 9,'seconds_late': -145726,'submitted_at': '2017-08-28T23:51:13Z','user_id': 42,'workflow_state': 'graded'}]Any help would be appreciated!!
