绘制没有停用词的词云

Question

我正在寻找使用我的 pandas 数据框中的列绘制 Wordcloud

这是我的代码：

all_words=''.join(  [tweet for tweet in tweet_table['tokens'] ] ) 

word_Cloud=WordCloud(width=500, height=300, random_state=21, max_font_size=119).generate(all_words)

plt.imshow(word_Cloud, interpolation='bilinear')

我要绘制的列 tweet_table['tokens'] 如下所示：

0        [da, trumpanzee, follower, blm, balance, wp, g...
1        [counting, blacklivesmatter, received, trainin...
2        [okay, like, little, kids, pretty, smart, know...

                               ...

44716    [films, eleven, films, bravo, bad, ass, video,...
44717                       [everybody, give, listen, blm]

我上面的代码给出了以下错误：

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-227-4066d6d1a153> in <module>
      2 # REMOVE STOP WORDS
      3 
----> 4 all_words=''.join(  [tweet for tweet in tweet_table['tokens'] ] )


TypeError: sequence item 0: expected str instance, list found

请问如何解决这个错误？ tweet_table['token'] 列是 tokenized 并清除任何 stopwords

非常感谢

Ps：当我为此专栏使用类似代码时 tweet_table['clean_text'] 代码工作正常。

列 tweet_table['clean_text'] 如下所示：

0            You have a da trumpanzee follower in      ...

Answer 1

我刚刚修好了

allwords=''.join( str(tweet_table['tokens']))

word_Cloud=WordCloud(width=500, height=300, random_state=21,
                     max_font_size=119).generate(allwords)

plt.imshow(word_Cloud, interpolation='bilinear')

其中 tweet_table['tokens'] 没有任何停用词。否则，我们创建一个停用词列表并将其添加为下面的代码

from wordcloud import WordCloud,STOPWORDS

stopwords_newlist = ["https", "co"] + list(STOPWORDS)

allwords=''.join( str(tweet_table['tokens']))

word_Cloud=WordCloud(width=500, height=300, random_state=21, stopwords=stopwords_newlist,
                     max_font_size=119).generate(allwords)


plt.imshow(word_Cloud, interpolation='bilinear')
