python批量修改文件名，添加前缀或后缀

[python]代码库

import os

def add_prefix_suffix_to_files(directory, prefix='', suffix=''):
    # 获取目录中的所有文件
    for filename in os.listdir(directory):
        # 获取文件扩展名
        file_ext = os.path.splitext(filename)[1]
        # 构建新的文件名
        new_name = f"{prefix}{filename}{suffix}{file_ext}"
        
        # 完整的旧文件路径和新文件路径
        old_file = os.path.join(directory, filename)
        new_file = os.path.join(directory, new_name)

        # 重命名文件
        os.rename(old_file, new_file)
        print(f'Renamed: {old_file} to {new_file}')

# 使用示例
directory_path = '/path/to/your/directory'  # 替换为你的目录路径
prefix = 'prefix_'  # 自定义前缀
suffix = '_suffix'  # 自定义后缀
add_prefix_suffix_to_files(directory_path, prefix, suffix)
