Solve the following python programming problem given the following code:
def method_decorator(decorator) : 
    '
    Converts a function decorator into a method decorator
    ' 
    def _dec(func) : 
        def _wrapper(self, * args, **kwargs) : 
            def bound_func(* args2, **kwargs2) : 
                return func (self, * args2, ** kwargs2) 
return decorator (bound_func) (* args, ** kwargs) 
return wraps (func) (_wrapper) 
update_wrapper (_dec, _dec) 
    _dec.__name__ = ('method_decorator(%s)' % decorator.__name__) 
    return _dec 

    
    

    Fix the buggy line: update_wrapper (_dec, _dec)
assistant
#Here is Python code to fix the buggy line: update_wrapper (_dec, _dec)
.

update_wrapper (_dec, decorator)
