class creates own objekts

Question

Is it possible for a class to create a number of objects n if I assign n a value? Assuming I have 100 cars that are identical and I want to create an object for each car, I could call a class that creates 100 objects (cars). I couldn't find anything about it on the internet and I don't know what exactly to look for. thanks for the replies

You should start by showing us a "use case". This could clarify the question and your needs. — Demi-Lune, Aug 29 '22 at 12:33
does that solve it? class_objects = [MyClass() for i in range(100)] — Yoav Sheetrit, Aug 29 '22 at 12:33

You could make use of a static factory method:

class Car:
  def __init__(self, ...):
    ...
  
  @classmethod
  def make_car_array(cls, n=100):
    return [Car() for i in range(n)]

and then call

array_of_cars = Car.make_car_array()

You probably meant `@staticmethod` ... – Demi-Lune Aug 29 '22 at 12:43
@Demi-Lune why? – matszwecja Aug 29 '22 at 12:45
Because the code doesn't work :-) `TypeError: 'type' object cannot be interpreted as an integer`. @classmethod passes the class as 1st argument `def f(cls, *other_args)`. Cf.

@Demi-Lune You're right, I missed that, my bad. First argument added. – Captain Trojan Aug 29 '22 at 18:01
