在沒有 NLTK 的情況下刪除文本文件中的停用詞

Question

我有 2 個文件： stopwords.txt和a.txt
我想刪除文件從停用詞stopwords.txt的文件a.txt ，並用空格隔開。

我該怎么做？ 這就是我試圖做的：

def remove_stopwords(review_words):
with open('stopwords.txt') as stopfile:
    stopwords = stopfile.read()
    list = stopwords.split()
    print(list)
    with open('a.txt') as workfile:
        read_data = workfile.read()
        data = read_data.split()
        print(data)
        for word1 in list:
            for word2 in data:
                if word1 == word2:
                    return data.remove(list)
                    print(remove_Stopwords)

提前致謝

Answer 1

下面是一個例子：

k = []
z = []
with open('stopWords.txt', 'r') as f:
   for word in f:
        word = word.split('\n')
        k.append(word[0])

with open('a.txt', 'r') as f_obj:
    for u in f_obj:
        u = u.split('\n')
        z.append(u[0])

p = [t for t in z if t not in k]
print(p)

遍歷停用詞文件中的每個單詞並將其附加到列表中，然后遍歷另一個文件中的每個單詞。 執行列表理解並刪除出現在停用詞列表中的每個單詞。

Answer 2

a.txt :

good great bad

stopwords.txt ：

good bad

也許：

with open('a.txt','r') as f, open('stopwords.txt','r') as f2:
   a=f.read().split();b=f2.read().split()
   print(' '.join(i for i in a if i.lower() not in (x.lower() for x in b)))
