How to instantiate object using iterable in Python?

Question

I need to instantiate an object using iterable with multiple objects inside. I have to create another method to do it

class MyClass:

  def __init__(self, *args):
    self.args = args

  def instantiate_from_iterable
     #some clever code

I need to have a result like this

MyClass.instantiate_from_iterable([1, 5, 3]) == MyClass(1, 5, 3)

MyClass.instantiate_from_iterable((3, 1, 7)) == MyClass(3, 1, 7)

I have no idea how to do this. If someone could help, I would appreciate it very much!

classmethod is what what you're after:

from collections.abc import Iterable

class MyClass:
    def __init__(self, *args):
        self.args = args
   
    @classmethod
    def instantiate_from_iterable(cls, args: Iterable):
        return cls(*args)

    
a = MyClass(1, 5, 7)
b = MyClass.instantiate_from_iterable([1, 5, 7])
     
print(a.args)  # -> (1, 5, 7)
print(b.args)  # -> (1, 5, 7)
