def __init__(self, required1, required2, default1='d1', default2='d2',
**kwargs):
   for par in kwargs:
      self.setattr(par, kwargs[par])
   self.required1 = required1
   self.required2 = required2
   self.default1 = default1
   self.default2 = default2

or

def __init__(self, required1, required2, default1='d1', default2='d2',
**kwargs):
   for par in kwargs:
      self.setattr(par, kwargs[par])
   self.required1 = required1
   self.required2 = required2
   self.default1 = default1
   self.default2 = default2
