05.05.2020 · However the above approach won't account for duplicate elements in the lists, the output elements can either be 0 or 1.If that is the behavior you're expecting instead, you could join the lists into strings and then use a CountVectorizer, since it is expecting strings:. text = df["comment text"].map(' '.join) count_vec = CountVectorizer() cv = count_vec.fit(text) …
