仅重命名文件夹中每个文件名的特定部分

import os

def rename_files(folder_path, old_part, new_part):
    for filename in os.listdir(folder_path):
        if filename.endswith('.txt'):  # 可以根据文件类型进行筛选
            new_filename = filename.replace(old_part, new_part)
            os.rename(os.path.join(folder_path, filename), os.path.join(folder_path, new_filename))

# 示例用法
folder_path = '/path/to/folder'  # 文件夹路径
old_part = 'old'  # 需要替换的部分
new_part = 'new'  # 替换后的新内容
rename_files(folder_path, old_part, new_part)
