python - student() 没有参数错误。我试图检查一切，任何人都可以帮我解决它

Question

class Student:
  def __init__(self,name,age,grade):
    self.name = name
    self.age = age
    self.grade = grade # 0 - 100

  def get_grade(self):
    return self.grade
class Course:
  def __init__(self,name,max_students):
    self.name = name
    self.max_students = max_students
    self.students = []

  def add_student(self,student):
    if len(self.students)<self.max_students:
      self.students.append(student)
      return True
    return False

  def get_average_grade(self):
    pass

我收到如下错误，我添加了两个下划线也不知道我在哪里弄错了
