好的，根据你的要求，将以上代码修改为将修改后的文件命名恢复原来的命名，可以按照以下方式修改：

import os 
from datetime import datetime 
import random 
import string 

def restore_original_names(folder_path): 
    """ 
    批量将文件名恢复为原来的名称，需要在修改文件名之前备份原来的名称 
    :param folder_path: 文件夹路径 
    """ 
    for filename in os.listdir(folder_path): 
        full_path = os.path.join(folder_path, filename) 
        if os.path.isfile(full_path): 
            # 获取备份的文件名 
            backup_filename = os.path.splitext(filename)[0] + ".bak" 
            backup_full_path = os.path.join(folder_path, backup_filename) 
            if os.path.exists(backup_full_path): 
                # 将备份的文件名恢复为原来的文件名 
                os.rename(backup_full_path, full_path) 

def batch_rename_files(folder_path, random_string_length=0): 
    """ 
    批量重命名文件，名字改为该文件的创建或修改日期，如果有重名的文件，可以添加一个随机字符串 
    :param folder_path: 文件夹路径 
    :param random_string_length: 随机字符串长度，默认为0 
    """ 
    # 先将文件名备份 
    for filename in os.listdir(folder_path): 
        full_path = os.path.join(folder_path, filename) 
        if os.path.isfile(full_path): 
            # 获取文件的后缀名 
            file_extension = os.path.splitext(filename)[1] 
            # 备份原来的文件名 
            backup_filename = os.path.splitext(filename)[0] + ".bak" 
            backup_full_path = os.path.join(folder_path, backup_filename) 
            os.rename(full_path, backup_full_path) 

    # 批量重命名文件 
    for filename in os.listdir(folder_path): 
        full_path = os.path.join(folder_path, filename) 
        if os.path.isfile(full_path): 
            # 获取文件的创建时间或修改时间 
            timestamp = os.path.getmtime(full_path) 
            # 格式化时间 
            date_time = datetime.fromtimestamp(timestamp) 
            new_name = date_time.strftime("%Y-%m-%d %H-%M-%S") 
            # 添加随机字符串 
            if random_string_length > 0: 
                random_string = ''.join(random.choices(string.ascii_lowercase + string.digits, k=random_string_length)) 
                new_name += '-' + random_string 
            # 拼接新的文件名 
            new_filename = new_name + file_extension 
            new_full_path = os.path.join(folder_path, new_filename) 
            # 重命名文件 
            os.rename(full_path, new_full_path) 

    # 将文件名恢复为原来的名称 
    restore_original_names(folder_path) 

if __name__ == '__main__': 
    folder_path = 'your_folder_path' 
    batch_rename_files(folder_path, random_string_length=5)

这个修改后的代码首先会备份原来的文件名，然后批量重命名所有的文件，并最后将所有文件的名字恢复为原来的名称。
