Call constructor of cls object in Python -

i trying call constructor of class object in python. managed work using following few lines:

obj = cls.__new__(cls) n = (list of attribute names) v = (list of attribute values)  s in n:     setattr(obj, s, v[s]) 

i wondering if there way directly insert attribute value + name pairs constructor, cause arguments ignored if call following:

obj = cls.__new__(cls, v) 

p.s.: using python3

the class looks similar this:

class inheritingclass(baseclass):     def __init__(self, basic_attribute, another_attribute=none):         super().__init__(basic_attribute=basic_attribute)         self.another_attribute= another_attribute  class baseclass:     def __init__(self, basic_attribute=1):        self.basic_attribute= basic_attribute 

so nothing special there

__init__ constructor of python class instead of __new__. refer pythons use of new , init more information.
