Solve the following python programming problem given the following code:
def generator(f) : 
    'Similar to the :func:`processor` but passes through old values
    unchanged and does not pass through the values as parameter.
    ' 
    @ processor 
    def new_func(stream, * args, **kwargs) : 
        for item in stream : 
            (yield item) 
for item in f (* args, ** kwargs) : 
            (yield item) 
return update_wrapper (f, f) 

    
    

    Fix the buggy line: return update_wrapper (f, f)

#Here is Python code to fix the buggy line: return update_wrapper (f, f)
.

return update_wrapper (def new_func(, f)
