Python 3.7 AttributeError: 'list' object has no attribute 'split'

Question

我正在尝试从每行都有一个句子的 csv 文件中进行情绪分析。

代表：

print(your_list)
[['Patience and Kindness and I know they truly love and care for animals, my dog also enjoys the events like seeing Santa and the Easter Bunny'], ['They are so sweet to my pets and try to fit them into the schedule when needed'], ['they call and check on our pet a day or 2 after visit make sure we fully understand treatment before we leave'], ['every member of the staff understands how our pets are our family; we never feel rushed and always have or questions answered, and are given reassurance if and when needed; they are compassionate and kind, respectful and very caring'], ['They made it a very peaceful experience when we had to put our pug to sleep '], ['They interact with my dogs and you can see the care they have for them.'], ['they make every effort to accomodate us']    


    from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer

        import csv
        with open('Before.csv', "r", errors='ignore') as f:
            reader = csv.reader(f)
        your_list = list(reader)

    print(your_list)

    analyser = SentimentIntensityAnalyzer()

    def print_sentiment_scores(sentence):
        snt = analyser.polarity_scores(sentence)
        print("{:-<40} {}".format(sentence, str(snt)))

    print_sentiment_scores(your_list)

但是，我收到以下错误：

analyser = SentimentIntensityAnalyzer()

def print_sentiment_scores(sentence):
    snt = analyser.polarity_scores(sentence)
    print("{:-<40} {}".format(sentence, str(snt)))


print_sentiment_scores(your_list)

回溯（最近调用最后）：

  File "<ipython-input-24-a7a32425d261>", line 8, in <module>
    print_sentiment_scores(your_list)

  File "<ipython-input-24-a7a32425d261>", line 4, in print_sentiment_scores
    snt = analyser.polarity_scores(sentence)

  File "C:\Users\abc\AppData\Local\Continuum\anaconda3\lib\site-packages\vaderSentiment\vaderSentiment.py", line 248, in polarity_scores
    text_token_list = text.split()

AttributeError: 'list' object has no attribute 'split'

.split(" ") your_list 上的函数没有帮助

Answer 1

SentimentIntensityAnalyzer.polarity_scores(text) 作为参数 text/str。你传递列表列表。可能您想将文件的全部内容作为单个文本传递或单独传递每个句子，而不是列表列表。

Answer 2

问题出在函数'print_sentiment_scores'的调用上。传递的参数是一个列表。根据您的要求，我认为您可以传递列表的元素来进行拆分。 Split() 根据文档 here

适用于字符串类型

Answer 3

Vader 的 'polarity_scores(sentence)' 采用字符串参数，而不是列表。

您的代码应该是：

analyser = SentimentIntensityAnalyzer()

def print_sentiment_scores(alist):
    for aSentence in alist: 
      aSnt = analyser.polarity_scores(aSentence[0])
      print(str(aSnt))


print_sentiment_scores(your_list)

所以我终于可以使用以下代码和 csv：

#!/usr/bin/python3
import csv
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer

with open('Before.csv', "r", errors='ignore') as f:
    reader = csv.reader(f)
    your_list = list(reader)

analyser = SentimentIntensityAnalyzer()

def print_sentiment_scores(alist):
    for aSentence in alist: 
      aSnt = analyser.polarity_scores(aSentence[0])
      print(str(aSnt))

print_sentiment_scores(your_list)

关联的 .csv 内容：

['Patience and Kindness and I know they truly love and care for 
animals, my dog also enjoys the events like seeing Santa and the Easter 
Bunny'], ['They are so sweet to my pets and try to fit them into the 
schedule when needed'], ['they call and check on our pet a day or 2 after 
visit make sure we fully understand treatment before we leave'], ['every 
member of the staff understands how our pets are our family; we never feel 
rushed and always have or questions answered, and are given reassurance if 
and when needed; they are compassionate and kind, respectful and very 
caring']

输出：

如果要格式化输出字符串，请对字符串格式进行一些研究。或者 post 关于 SO 的另一个问题，如果你找不到答案。
