如何循环这个代码，每一个学生得分50分，就会增加1颗星。

Question

事先道歉，但我是蟒蛇的初学者，而且还在学习。我遇到了这个问题，学生在比赛中每赚50分，就会在他们的信息中添加1颗星。但我似乎做不到，这是我的代码；

class points:
    def __init__ (self, studentname, points, star):
        self.studentname = studentname
        self.points = points
        self.star = star

    def play (self, totalpoints):
        self.points += totalpoints

        #every time the students score 50, they will have plus 1 star
        if self.points == 50:
            self.star += 1

    def displayInfo (self):
        print (self.studentname)
        print(self.points)
        print(self.star)

student1 = points("Ana", 0, 0)
student2 = points("Sandra", 0, 0)

student1.displayInfo()
student2.displayInfo() #will display their information before playing

student1.play(10)
student2.play(5)
student1.play(20)
student2.play(10)
student1.play(30)
student2.play(30)
student1.play(10)
student2.play(5)
student1.play(20)
student2.play(10)
student1.play(30)
student2.play(30)

student1.displayInfo()
student2.displayInfo() #will display their information after playing

当一个学生到达时，你只会添加一颗星，正好是50分，再也不会了。在play()方法中，您可以做的是更新玩家每次添加点数时拥有的星星数，如下所示：

def play(self, totalpoints):
    self.points += totalpoints
    self.star = self.points // 50

这使用Python's floordiv operator (//)
