在python中获取停用词列表时出现错误

Question

我正在运行以下代码

from rake_nltk import rake
import operator
stoppath = 'data/stoplists/SmartStoplist.txt'
rake_object = rake.Rake("SmartStopList.txt",5,3,2)

但是当我运行最后一行时，我得到以下错误

rake_object = rake.Rake("SmartStopList.txt",5,3,2)
Traceback (most recent call last):

  File "<ipython-input-12-595e49e89adb>", line 1, in <module>
    rake_object = rake.Rake("SmartStopList.txt",5,3,2)

  File "C:\Users\kris\Anaconda3\lib\site-packages\rake_nltk\rake.py", line 64, in __init__
    self.to_ignore = set(chain(self.stopwords, self.punctuations))

TypeError: 'int' object is not iterable

我不确定为什么会出现此错误。需要帮助

Answer 1

看看__init__

def __init__(
    self,
    stopwords=None,
    punctuations=None,
    language="english",
    ranking_metric=Metric.DEGREE_TO_FREQUENCY_RATIO,
    max_length=100000,
    min_length=1,
)

5 将指向punctuations 参数，该参数应该是一个列表，而不是ranking_metric。使用参数名称

rake_object = rake.Rake("SmartStopList.txt", ranking_metric=5, max_length=3, min_length=2)

顺便说一下stopwords也应该是一个列表，你正在发送字符串。
