I have written a code that collects student's assignment/exam results and puts into a list of student dictionary object. Within the code there is also a dictionary that consist of the weightage of each assignment or exam. This then allows me to calculate the weighted results. How can I implement error handling into this code so that an error can be raised if weights dictionary contains entries that don't match the ones stored in the student dictionary?
For example: Student Dict: A1, A2, A3 Weights: A1, E1 (Error is raised since E1 isn't present)
[Current code]
class Student:
# Part 1a: Creating student class
def __init__(self, stud_dict):
self.name = stud_dict['name']
self.results = stud_dict['results'].copy()
# Part 2: Getting weighted result
def get_weighted_result(self, weights):
result = 0
for key in weights:
result += weights[key] * self.results[key]
return result
# Part 1b: Converting student dictionary list to student object list
def dict_to_class_obj(stud_dicts):
students = []
for stud_dict in stud_dicts:
students.append(Student(stud_dict))
return students
#Test Section
stud_dicts = [
{
"name": "Fus Ro Dah",
"results": {
"assignment_1": 10,
"assignment_2": 10,
"examination_1": 10,
}
},
{
"name": "Foo Barry",
"results": {
"assignment_1": 1,
"assignment_2": 2,
"examination_1": 3,
}
},
]
# creating Student objects list
students = dict_to_class_obj(stud_dicts)
print(students[0].name)
print(students[0].results)
print(students[0].get_weighted_result({"assignment_1": 1.0, "examination_1": 9.0}))
