I created a simple Student list and wish to append manual student objects created, using the method below. It comes up with an error saying it requires an additional argument.

class Student:
    def __init__(self, first_name, last_name, student_num, email, pps, middle_name):
        self.first_name = first_name
        self.last_name = last_name
        self.student_num = student_num
        self.email = email
        self.__pps = pps
        self.__middle_name = middle_name
        self.student_list =[]


    def get_full_details(self):
        details = self.first_name   " "   self.last_name   " "   str(self.student_num)   " "   self.email
        return details


    def add_student(self, student_object):
        return self.student_list.append(student_object)



# Creating 4 student objects
student1 = Student("Jimmy", "Mccarthy", 1234, "[email protected]", 8074454, "Edward")
student2 = Student("James", "Flynn", 5678, "[email protected]", 7367736, "Borck")
student3 = Student("Emma", "Mcgath", 9837, "[email protected]", 3455433, "Richei")
student4 = Student("Echo", "O Leary", 4334, "[email protected]", 4333357, "Wei")

Student.add_student(student1)

CodePudding user response：

If you call Student.add_student, you need 2 arguments: self, student_object. You can solve this if you first call the constructor of the class student1 = Student("Jimmy", "Mccarthy", 1234, "[email protected]", 8074454, "Edward"), then use add_student on student1: student1.add_student(Student("James", "Flynn", 5678, "[email protected]", 7367736, "Borck")).
