Question

运行我的程序时，我收到此错误消息。我不太确定发生了什么，但应该发生的是该程序应该测试一个老学生是否已经注册了课程，如果是这样，新学生将被添加到该课程，否则将创建一个新的课程大学班级注册。

from scipy.odr.odrpack import Output
class Student:

    def __init__ (self,Name,Degree,ID):
        self.courses = []
        self.name = Name
        self.degree = Degree
        self.id = ID

    def takecourse (self,course_Name):
        self.courses.append(course_Name)

    def studentOverview (self):
        print self.name
        print self.id
        print self.degree
        print "Courses:"
        for course in self.courses:
            print course


class University:

        for key in self.Registry.keys():

                output+='\n'
            return output
