Solve the following python programming problem given the following code:
def Transform(self, client, photo, callback) : 
    from viewfinder.backend.storage.s3_object_store import S3ObjectStore 
    def _SetPhotoMD5Values(md5_values) : 
        (tn_md5, med_md5, full_md5, orig_md5) = md5_values 
        assert ((photo.tn_md5 == tn_md5) or (photo.tn_md5 is None)), photo 
        photo.tn_md5 = tn_md5 
        assert ((photo.med_md5 == med_md5) or (photo.med_md5 is None)), photo 
        photo.med_md5 = med_md5 
        assert ((photo.full_md5 == full_md5) or (photo.full_md5 is None)), photo 
        photo.full_md5 = full_md5 
        assert ((photo.orig_md5 == orig_md5) or (photo.orig_md5 is None)), photo 
        photo.orig_md5 = orig_md5 
        photo.placemark = photo.placemark 
        self._LogUpdate (photo) 
        if Version._mutate_items : 
            photo.Update (client, partial (callback, photo)) 
else : 
            callback (photo) 
def _OnFetchHead(head_callback, response) : 
        if (response.code != 404) : 
            etag = response.headers ['Etag'] [1 : (- 1)] 
else : 
            etag = None 
head_callback (etag) 
def _SendHeadRequest(photo_id, suffix, head_callback) : 
        object_store = S3ObjectStore ('photos-viewfinder-co') 
        url = object_store.GenerateUrl ((photo_id + suffix), method = 'HEAD') 
        http_client = httpclient.AsyncHTTPClient () 
        http_client.fetch (url, method = 'HEAD', callback = partial (_OnFetchHead, head_callback)) 
client_data = photo.client_data 
    if ((client_data is None) or ('tn_md5' not in client_data)) : 
        if (not Version._allow_s3_queries) : 
            callback (photo) 
            return 
with util.ArrayBarrier (_SetPhotoMD5Values) as b : 
            _SendHeadRequest (photo.photo_id, '.t', b.Callback ()) 
            _SendHeadRequest (photo.photo_id, '.m', b.Callback ()) 
            _SendHeadRequest (photo.photo_id, '.f', b.Callback ()) 
            _SendHeadRequest (photo.photo_id, '.o', b.Callback ()) 
else : 
        _SetPhotoMD5Values ((client_data ['tn_md5'], client ['med_md5'],...

    
    

    Fix the buggy line: _SetPhotoMD5Values ((client_data ['tn_md5'], client ['med_md5'], photo.full_md5, photo.orig_md5))

#Here is Python code to fix the buggy line: _SetPhotoMD5Values ((client_data ['tn_md5'], client ['med_md5'], photo.

_SetPhotoMD5Values ((client_data ['tn_md5'], client_data ['med_md5'], photo.full_md5, photo.orig_md5))
