Solve the following python programming problem given the following code:
@ classmethod 
def _add_delegate_accessors(cls, delegate, accessors, typ, overwrite = False) : 
    "
        add accessors to cls from the delegate class

        Parameters
        ----------
        cls : the class to add the methods/properties to
        delegate : the class to get methods/properties & doc-strings
        acccessors : string list of accessors to add
        typ : 'property' or 'method'
        overwrite : boolean, default False
           overwrite the method/property in the target class if it exists
        " 
    def _create_delegator_property(name) :

def _setter(self, new_values) : 
            return self._delegate_property_set (name, new_values) 
_getter.__name__ = name 
        _setter.__name__ = name 
        return property (fget = _getter, fset = _setter, doc = getattr (delegate, name).__doc__) 
def _create_delegator_method(name) : 
        def f(self, * args, **kwargs) :
