Question

我正在将“ list”功能应用于包含生成器对象的熊猫col，以尝试显示col中的所有生成器对象。申请时，col返回空列表。 'subject_verb_object_triples'是文本功能（https://chartbeat-labs.github.io/textacy/_modules/textacy/extract.html）

打印（sp500news3）

date_publish    title
79944   2007-01-29 19:08:35 <generator object subject_verb_object_triples at 0x1a42713550>
181781  2007-12-14 19:39:06 <generator object subject_verb_object_triples at 0x1a42713410>
213175  2008-01-22 11:17:19 <generator object subject_verb_object_triples at 0x1a427135f0>
93554   2008-01-22 18:52:56 <generator object subject_verb_object_triples at 0x1a427135a0>

In []: sp500news3["title"].apply(list)
Out []: 79944     []
        181781    []
        213175    [] ...

期望的输出是元组，例如：

[(Sky proposal, is, matter), (Sky proposal, is, Mays spokesman)], 
[(Women, lag, Intel report)], 
[(Amazon, expected, to unveil)], 
[(Goldman Sachs, raising, billion)], 
[(MHP, opens, books)], 
[(Disney, hurls, magic), (Disney, hurls, moolah)], 
[(Amazon, offering, loans), (Amazon, offering, to)], ....

如何在数据框中显示预期的输出？

Answer 1

我已经测试了以下代码，并且工作正常

import textacy
import pandas as pd
from textacy import preprocessing
pd.options.display.max_colwidth=-1
df['<New Column name'>]=df['<Your column name that needs to be processed>'].apply(lambda x:preprocessing.normalize_whitespace(preprocessing.remove_punctuation(str(x))))

如何在熊猫df中将列表函数应用于textacy生成器obj
