python-3.x - 向类添加方法以比较 Python 中的对象，但我的代码中不断出现错误

Question

这是我的任务：向比较两个 Student 对象的 Student 类添加方法。一种方法应该测试是否相等。其他方法应该支持其他可能的比较。在每种情况下，该方法都会返回两个学生姓名的比较结果。但由于某种原因，我不断收到错误消息。我不确定我做错了什么。

class Student(object):
def __init__(self, name, number):


self.name = name
self.scores = []
for count in range(number):
  self.scores.append(0)

def getName(self):


return self.name


# method to set the score
def setScore(self, i, score):


self.scores[i - 1] = score


# method to get the score
def getScore(self, i):


return self.scores[i - 1]


# method to get the average
def getAverage(self):


return sum(self.scores) / len(self._scores)


# method to get the high score
def getHighScore(self):


  return max(self.scores)


# method to print the object in string format
def __str__(self):


return "Name: " + self.name + "\nScores: " + \
  " ".join(map(str, self.scores))


# checking for equality for the names
 def __eq__(self,other):


if self.name == other.name:
  return "Equal"
else:
  return "Not Equal"


# checking for less than in names
def __lt__(self,other):


if self.name < other.name:
  return "Less than"   
else:
  return "Not less than"


# checking for greater than or equal to names
 def __ge__(self,other):


if self.name >other.name:
  return "Greater than"
elif self.name == other.name:
  return "Both are equal"
else:
  return "Not greater or equal"




# main function
def main():


# creating student object
  student = Student("Sofia", 5)
  print(student)
  for i in range(1, 6):
  student.setScore(i, 100)
  print(student)


# creating student2 object
student2= Student("Dom",5)
print(student2)
for i in range(1, 6):
student2.setScore(i, 100)
print(student2)

# checking the equality methods
print(student==student2)
print(student<student2)
print(student2<student)
print(student>=student2)




# calling the main function
if __name__ == "__main__":
 main()
