我试图制作一个python脚本，该脚本从txt文件中删除不必要的单词和标点符号。但是，对于分级机还不够好吗？

Question

我正在尝试制作一个单词云。我需要剥离一个无趣单词和标点符号的TXT文件。分级器只是没有给我任何反馈。我认为我的脚本消除了一些额外的单词，我不知道为什么。有人可以将我指向正确的方向吗？

punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
uninteresting_words = ["the", "a", "to", "if", "is", "it", "of", "and", "or", "an", "as", "i", "me", "my", \
"we", "our", "ours", "you", "your", "yours", "he", "she", "him", "his", "her", "hers", "its", "they", "them", \
"their", "what", "which", "who", "whom", "this", "that", "am", "are", "was", "were", "be", "been", "being", \
"have", "has", "had", "do", "does", "did", "but", "at", "by", "with", "from", "here", "when", "where", "how", \
"all", "any", "both", "each", "few", "more", "some", "such", "no", "nor", "too", "very", "can", "will", "just"]

def count(file_contents):
    frequencies = {}
    word_list = file_contents.split()
    final_list = []
    #remove all uninteresting words
    for word in word_list:
    
        new_word = ""
        for character in word:
            if character not in punctuations and character.isalpha():
                new_word += character
            
        if word.lower() not in uninteresting_words:
            final_list.append(new_word)
        
    for word in final_list:
        if word not in frequencies:
            frequencies[word] = 0 
        frequencies[word] += 1
    return frequencies

Answer 1

我不知道我是否没有错误的答案，因为我将其上传错误，或者是否被漏了，因为我以两种不同的方式提交了此代码。我直接单击的一个提交作业；另一个，我下载了笔记本并通过Coursera提交。这奏效了，它给了我正确的答案。无论如何，这是正确的代码。

# Here is a list of punctuations and uninteresting words you can use to process your text
punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
