**hello good afternoon, I have the following problem of the title statement, I want my method of adding course and reporting to depend on registering new courses and not joining each other because I was doing tests, an example when having two registers of new students and add courses at the time of reporting, I get the courses of the first record plus the second. yes please help me to find the solution. **

CodePudding user response：

You are using the courseList as a global variable, so any courses which are added by any student will be shared by all the students. Instead add the courseList as a member of the Student class first.

class Student:
def __int__(self, studentCod, name):
self.studentCod = studentCod
self.name = name
self.courseList = list()

Then add the courses to the respective student's list.

for student in studentList:
 if student.codStudent == codStudent:
    course = Courses()
    course.CourseName = input("Enter the course name: ")
    student.courseList.append(course)
