通过文件名更改多个文件的内容

import os

def change_file_content(directory, old_content, new_content):
    for filename in os.listdir(directory):
        if filename.endswith(".txt"):  # 只处理txt文件，可以根据实际需求修改文件类型
            file_path = os.path.join(directory, filename)
            with open(file_path, 'r') as file:
                content = file.read()
            
            if old_content in content:
                new_content = content.replace(old_content, new_content)
                with open(file_path, 'w') as file:
                    file.write(new_content)

# 示例调用
directory = '/path/to/files'  # 文件所在目录
old_content = '旧内容'
new_content = '新内容'
change_file_content(directory, old_content, new_content)
