    Please repeat the intro tour; focus on [MRE](https://stackoverflow.com/help/minimal-reproducible-example). – Prune Apr 14 '20 at 16:11

    Please add description as to what you're actually asking. – Yoel Nisanov Apr 14 '20 at 16:13
  • Don't pass `self` to `super().__init__()` – Mark Apr 14 '20 at 16:13

    Your immediate problem is exactly what the message tells you. Remember that `self` is an implied argument when you call a class method. – Prune Apr 14 '20 at 16:13
  • You could try using: `super(Infant, self).__init__(name, age)` – garglblarg Apr 14 '20 at 16:43
  • Does this answer your question? [\_\_init\_\_() takes from 1 to 3 positional arguments but 4 were given](https://stackoverflow.com/questions/20209415/init-takes-from-1-to-3-positional-arguments-but-4-were-given) – Joe Apr 14 '20 at 17:20

ash=Infant('Yash',21)

ash.add_vac('MMR')

print(ash.get_details())

this is only for ash instance ok, x, y is another instance.

  • Please do not just code dump as an answer. Explain how this code answers the question and why. – Object object Apr 14 '20 at 18:47
  • so you don't need to pass the self parameter(in any class function super().__init__(self, name, age)), and second, you can not use f string format multiple times in single string(in get_details function). and you can find out your question's answer by comparing bothe programs – A D Apr 18 '20 at 09:05
