如何使用python和bs4读取和覆盖文件夹中的所有*.txt文件？

import os
from bs4 import BeautifulSoup

def read_and_replace_txt_files(folder_path):
    # 遍历文件夹中的所有文件和子文件夹
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            if file.endswith(".txt"):
                file_path = os.path.join(root, file)
                # 打开文件并读取内容
                with open(file_path, "r") as f:
                    content = f.read()
                # 使用BeautifulSoup解析内容
                soup = BeautifulSoup(content, "html.parser")
                # 对内容进行修改
                # 这里可以根据具体需求进行操作，例如替换文本、添加标签等
                modified_content = soup.prettify()
                # 覆盖原文件
                with open(file_path, "w") as f:
                    f.write(modified_content)

folder_path = "/path/to/folder"
read_and_replace_txt_files(folder_path)

pip install beautifulsoup4
