Rake error while getting stop words list in python

Question

I am running the following code

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

But when i run the last line i get the below error

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

I am nt sure why am i getting this error. Need help on the same

Answer 1

Have a look at the __init__

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

The 5 is going to punctuations parameter which is expected to be a list, not to ranking_metric. Use the parameter names

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

By the way stopwords is also expected to be a list, you are sending string.
