add object and name in list
#1
Hi! How can I add in both list (in first fname and in second the person object) every time when I creat a Person?
Secondary how can I add in a list online students?
Thanks!

class Person:
    name_persons = []
    object_persons = []

    def __init__(self, fname, lname, cnp, age):
        self.fname = fname
        self.lname = lname
        self.cnp = cnp
        self.age = age

    @staticmethod
    def add_person(self, fname):
        self.name_persons.append(fname)

    def gender(self):
        if str(self.cnp)[0] == 1:
            return "m"
        return 'f'

    
class Student(Person):
    def __init__(self, nume, prenume, cnp, varsta, medie):
        super().__init__(nume, prenume, cnp, varsta)
        self.medie = medi

In the __init__()
self.persons.append(self) 
This saves the Person object which has the name as an attribute. No need for two lists. Actually far better than two lists.

Drop the add_person method. gender will always return 'f'.

It works. I would never have thought of that! Thanks!

I'm back with another problem, now I add a person to the list, but if I run the program again, it deletes that person and adds the newly added person. How do I keep the previously added person, should that list be outside the class?

Of course, you can also store all necessary information e.g. as regular txt/csv or JSON, etc. format and recreate the objects, e.g. https://stackoverflow.com/a/33245595/4046632
