Проверка работы классов

lecturer = Lecturer('Иван', 'Иванов')
reviewer = Reviewer('Пётр', 'Петров')

print(isinstance(lecturer, Mentor)) # True
print(isinstance(reviewer, Mentor)) # True
print(lecturer.courses_attached) # []
print(reviewer.courses_attached) # []

Проверка, что функциональность родительского класса работает

best_student = Student('Ruoy', 'Eman', 'your_gender')
best_student.courses_in_progress += ['Python']

Reviewer может проверять домашние задания (наследует метод rate_hw)

reviewer.courses_attached += ['Python']
reviewer.rate_hw(best_student, 'Python', 10)
reviewer.rate_hw(best_student, 'Python', 9)

print(best_student.grades) # {'Python': [10, 9]}
