熊猫:遍历列表并在列中从列表中查找单词…使用“从列表中查找单词”创建新列

您可以尝试使用df.apply和set intersection查看文本列和单词列表中同时出现的单词。

您需要考虑当文本列中出现多个单词时会发生什么情况

def word_finder(x):
  df_words = set(x.split(' '))
  extract_words =  word_set.intersection(df_words)
  return ', '.join(extract_words)

df = pd.DataFrame(data = {'text' : ['hello you person', 'you have a dog', 'the bird flew', 'the horse is here', 'bird bird bird', 'dog and cat']})

word_set = {'dog', 'cat', 'horse', 'bird'}

df['extract'] = df.text.apply(word_finder)

输出

                text   extract
0   hello you person          
1     you have a dog       dog
2      the bird flew      bird
3  the horse is here     horse
4     bird bird bird      bird
5        dog and cat  dog, cat
