Q&A
'list' object has no attribute 'apply' 문의
아래와 같이 변형하셔서 적용하시면 될 듯 싶습니다.. count_words_f = lambda x: len(str(x).split()) train['num_words'] = list(map(count_words_f, clean_train_reviews)) count_uniq_words_f = lambda x: len(set(str(x).split())) train['num_uniq_words'] = list(map(count_uniq_words_f, clean_train_reviews))
