43# in my case, i messing the arguments in __new__ method, to decide which class
44# should to call and also be its attribute too.
45    # the __init__ method remains same
46    # the required arguments are specified
47
48# but i don't think this is good
49# because any arguments that passed __new__ method,
50# remains same (forced) in __init__ method, i no longer use it. so *args is
51# needed for dumping the arguments, or python will throw me an exception
52
53# actually i just wont write *args there, its unused ( ͡° ͜ʖ ͡°)
