Python list to store class instance?

Question

Given a python class class Student(): and a list names = []; then I want to create several instances of Student() and add them into the li

Answer 1

I'm fairly new to OOP, but does this not do what you want quite nicely? name_list is a class variable, and every time you create a new Student object, it gets added to Student.name_list. Say for example you had a method cheat(self) which you wanted to perform on the third student, you could run Student.name_list[2].cheat(). Code:

class Student():
    name_list = []
    def __init__(self, score, gender):
        Student.name_list.append(self)
        self.score = score
        self.gender = gender

    #this is just for output formatting
    def __str__(self):
        return "Score: {} || Gender: {}".format(self.score, self.gender)

#again for output formatting
def update(): print([str(student) for student in Student.name_list])

update()
Student(42, "female")
update()
Student(23, "male")
update()
Student(63, "male")
Student(763, "female")
Student("over 9000", "neutral")
update()

Output:

[]
['Score: 42 || Gender: female']
['Score: 42 || Gender: female', 'Score: 23 || Gender: male']
['Score: 42 || Gender: female', 'Score: 23 || Gender: male', 'Score: 63 || Gender: male', 'Score: 763 || Gender: female', 'Score: over 9000 || Gender: neutral']
