Solve the following python programming problem given the following code:
def __call__(self, func_or_cls) : 
    condition = self.condition 
    reason = self.reason 
    if inspect.isfunction (self) : 
        @ six.wraps (func_or_cls) 
        def wrapped(* args, **kwargs) : 
            if condition : 
                raise testtools.TestCase.skipException (reason) 
return func_or_cls (* args, ** kwargs) 
return wrapped 
else : 
        if inspect.isclass (func_or_cls) : 
            orig_func = getattr (func_or_cls, 'setUp') 
            @ six.wraps (orig_func) 
            def new_func(self, * args, **kwargs) : 
                if condition : 
                    raise testtools.TestCase.skipException (reason) 
orig_func (self, * args, ** kwargs) 
func_or_cls.setUp = new_func 
            return func_or_cls 
else : 
            raise TypeError ('skipUnless can be used only with functions or classes')
