将索引值替换为实际文件名

Question

我有以下代码：

import os
from sklearn.feature_extraction.text import TfidfVectorizer

path = 'some path'

textIN = [os.path.join(dirpath, f) for dirpath, dirnames, files in 
    os.walk(path) for f in files if f.endswith('.txt')]
docs = [open(f) for f in textIN]
print textIN
tfidf = TfidfVectorizer(input='file', encoding='utf-8', 
    stop_words='english', norm='l2').fit_transform(docs)
pair = tfidf * tfidf.T
print pair

它工作正常并输出以下内容：

[filename, filename, filename, etc.]

我希望能够用相应的文件名替换索引值，并显示所有结果。

感谢您的帮助。
