Hey, @xiaowenjie21, is this related to the book or is it a general Stack Overflow-type question?

From a quick look, replacing extract() with .extract_first('N/A') should fix the problem. item["title"] is an array with potentially more than one values. extract_first() (see here) takes just the first element.
