如何在文件列表中为文件夹中的所有文件添加前缀"_“[Python]

import os
import shutil

def add_prefix_to_files(folder_path, prefix):
    # 遍历文件夹中的所有文件
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            # 获取文件的绝对路径
            file_path = os.path.join(root, file)
            # 添加前缀
            new_file_name = prefix + file
            new_file_path = os.path.join(root, new_file_name)
            # 重命名文件
            os.rename(file_path, new_file_path)

folder_path = "文件夹路径"
prefix = "_"

add_prefix_to_files(folder_path, prefix)
