Python: добавление командной кнопки под названием «Построить результаты» в пользовательский интерфейс, которая отображае ⇐ Python

[Anonymous]

Я создаю программу, которая берет информацию об учениках и результаты тестов и генерирует графический интерфейс, который вычисляет их среднее значение, медиану, моду и стандартное отклонение. Также требуется наличие кнопки «Показать результаты», которая отображает линейный график результатов тестов учащегося. Однако я продолжаю сталкиваться со следующей ошибкой:

TypeError: StudentView.init() отсутствует 1 обязательный позиционный аргумент: 'студент '

Может кто-нибудь помочь мне понять, что я делаю не так с этим кодом. Я несколько раз пытался сделать это правильно.
Вот коды, с которыми я работаю:
student.py

class Student:
def __init__(self, student_id, name):
self.student_id = student_id
self.name = name
self.test_scores = []

def add_test_score(self, score):
self.test_scores.append(score)

def average_test_score(self):
if len(self.test_scores) == 0:
return 0
return sum(self.test_scores)/len(self.test_scores)

def get_test_scores(self):
return self.test_scores
