Copy multiple Excel files and name them different

The code is as follows ：

import os,shutil
import sys
result=[]
with open('name.txt','r',encoding='utf-8') as f:# A text list of names that need to be named 
    for line in f:
        result.append(list(line.strip('\n').strip().split(',')))
    print(result)

def copy_files():    # Define the function name 
    for i in result:
        j=i[0]
        for foldName, subfolders, filenames in os.walk(path):     # use os.walk Method acquisition path Folder path under path , Subfolder name , All filenames 
               for filename in filenames:                         # Traverse all file names under the list 
                    if filename.endswith('.xlsx'):                # When the file name is .txt At the end of suffix 
                            new_name=filename.replace('.xlsx','%s.xlsx'%(j))               # Give the file a new name 
                            shutil.copyfile(os.path.join(foldName,filename), os.path.join(path2,new_name))    # Copy to new path , And rename the file 
                            print(filename,"copied as",new_name)           # Output hint 

if __name__ == '__main__':
        path = r'D:\ Desktop files \test2'   # Before running the program , Remember to modify the home folder path ！
        path2 =r'D:\ Desktop files \test3'  # New path for storing files , Do not put it under the original path , Otherwise, two more copies will be made 
        copy_files()         # Call the defined function , Note that the name is consistent with the defined function name
