在Python中将目录传递给变量

我正在尝试修改GitHub的一个脚本,该脚本将访问TAR文件并对其进行处理。代码中有一个变量需要指向文件所在的根目录(我认为…)。代码如下:

def make_Dictionary(root_dir):
    emails_dirs = [os.path.join(root_dir,f) for f in os.listdir(root_dir)]    
    all_words = []       
    for emails_dir in emails_dirs:
        emails = [os.path.join(emails_dir,f) for f in os.listdir(emails_dir)]
        for mail in emails:
            with open(mail) as m:
                 for line in m:
                     words = line.split()
                     all_words += words
    dictionary = Counter(all_words)
    list_to_remove = dictionary.keys()

    for item in list_to_remove:
        if item.isalpha() == False: 
            del dictionary[item]
        elif len(item) == 1:
             del dictionary[item]
    dictionary = dictionary.most_common(4000)

    np.save('dict_movie.npy',dictionary) 

    return dictionary

root_dir = sys.path[0]
dictionary = make_Dictionary(root_dir)

root\u dir正在抛出:

  File "C:\Users\seand\eclipse-workspace\sentiment_project\src\root\nested\movie-polarity.py", line 22, in make_Dictionary
    emails = [os.path.join(emails_dir,f) for f in os.listdir(emails_dir)]
NotADirectoryError: [WinError 267] The directory name is invalid: 'C:\\Users\\seand\\eclipse-workspace\\sentiment_project\\src\\root\\nested\\movie-polarity-tfidf.py'

方向状态“注意:需要相应地设置movie-polarity-tfidf.py和movie-polarity.py中语料库的目录路径。”但我指定的路径包含脚本所需的语料库TAR文件。我不明白为什么,如果脚本正在查找目录,那么这个.py文件会被拾取。
