python 3.x - 使用正则表达式切割普通HTML文件

Question

我正在使用此代码提取本地存储的HTML文件的一部分，并将缩短的新文档保存到.txt文件中。

import glob
import os
import re

def extractor():
    os.chdir(r"F:Test")  # the directory containing your html
    for file in glob.iglob("*.html"):  # iterates over all files in the directory ending in .html
        with open(file, encoding="utf8") as f, open((file.rsplit(".", 1)[0]) + ".txt", "w", encoding="utf8") as out:
            contents = f.read()
            extract = re.compile(r'(Start).*?End', re.I | re.S)
            cut = extract.sub('', contents)
            if re.search(extract, contents) is not None:
                out.write(cut)
            out.close()
extractor()

它适用于我的大多数文件，但是对于一些文件，我确实有一些编码问题并得到：

Traceback (most recent call last):
  File "C:/Users/6930p/PycharmProjects/untitled/Versuch/CutFile.py", line 16, in <module>
    extractor()
  File "C:/Users/6930p/PycharmProjects/untitled/Versuch/CutFile.py", line 14, in extractor
    out.write(cut)
  File "C:Users6930pAnaconda3libencodingscp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 241205-241210: character maps to <undefined>

有人知道有什么问题吗？我认为通过使用encoding="utf8"我不会有任何问题编码......

任何帮助表示赞赏！

好的，这是encoding="utf8"的问题。它忘记用"utf8"编码我新创建的.txt文件。代码已更新并正常工作！
