python - 如何在 Python 中一个一个地从文件中读取标记？

Question

我遇到的问题是，在我的代码中，我无法获得与要从原始文本中删除的停用词相匹配的单个词/标记。相反，我得到的是一个完整的句子，因此无法将其与停用词相匹配。请告诉我一种方法，通过它我可以获得单个标记，然后将它们与停用词匹配并删除它们。请帮助我。

from nltk.corpus import stopwords
import string, os
def remove_stopwords(ifile):
    processed_word_list = []
    stopword = stopwords.words("urdu")
    text = open(ifile, 'r').readlines()
    for word in text:
         print(word)
         if word  not in stopword:
                processed_word_list.append('*')
                print(processed_word_list)
                return processed_word_list

if __name__ == "__main__":
    print ("Input file path: ")
    ifile = input()
    remove_stopwords(ifile)

试试这个:

from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize
import string, os, ast
def remove_stopwords(ifile):
    processed_word_list = []
    stopword = stopwords.words("urdu")
    words = ast.literal_eval(open(ifile, 'r').read())
    for word in words:
        print(word)
        if word not in stopword:
            processed_word_list.append('*')
        else:
            processed_word_list.append(word)
    print(processed_word_list)
    return processed_word_list

if __name__ == "__main__":
    print ("Input file path: ")
    ifile = input()
    remove_stopwords(ifile)
