Question

我收到了这个错误，我认为我已经完成了所需的参数，但我不确定我做错了什么以及这个错误究竟意味着什么。我收到此错误：TypeError：addQuiz（）缺少1个必需的位置参数：＆＃39;得分＆＃39;

这是我为学生创建的课程：

class Student:
    def __init__(self, name):
        self.name = name
        self.score = 0
        self.counter = 0

    def getName(self):
        return self.name

    def addQuiz(self, score):
        self.score += score
        self.counter += 1

    def get_total_score(self):
        return self.score

    def getAverageScore(self):
        return self.score / self.counter


from Student import Student

x = input("Enter a student's name: ")


while True:

    score = input("Enter in a quiz score (if done, press enter again): ")
    quiz_score = Student.addQuiz(score)
    if len(score) < 1:
        print(Student.getName(x), Student.get_total_score(quiz_score))
        break

修改

这些方法不是类方法，是实例方法，创建实例，并调用它们：

另外，更好地看一下，你有另一种问题，我会评论：

class Student:
    def __init__(self, name):
        self.name = name
        self.score = 0
        self.counter = 0

    def getName(self):
        return self.name

    def addQuiz(self, score):
        self.score += score
        self.counter += 1

    def get_total_score(self):
        return self.score

    def getAverageScore(self):
        return self.score / self.counter

###execution part (you can put it in a main... but as you want)


name = input("Enter a student's name: ") #create a variable name, and give it to the object you will create
student_you = Student(name) #here, the name as parameter now belongs to the object
score = float(input("Enter in a quiz score (if done, press enter again): ")) #you have to cast the input to a numerical type, such as float

while score > 1: #it is better to the heart of the people to read the code, to modify a "flag variable" to end a while loop, don't ask in a if and then use a break, please, just an advice
    score = float(input("Enter in a quiz score (if done, press enter again): ")) #here again, cast to float the score
    student_you.addQuiz(score) #modify your object with the setter method


print(student_you.getName(), student_you.get_total_score()) #finally when the execution is over, show to the world the result

TypeError：addQuiz（）缺少1个必需的位置参数：＆＃39;得分＆＃39;
