ソースコードを見てみましょう.

for i in range(1,6):
    file = i
    f = open(str(file) + ".txt","w")
    f.write("hello")
    f.close()

#         [vale]-
import os
foldername = input("input the folder you want to change:")
print(foldername)
#get_folder_file
file_names = os.listdir(foldername)

os.chdir(foldername)
#change_name
for name in file_names:
        print(name)
        os.rename(name,"[vale]-" + name)

#!/usr/bin/env python

import os            #    

#                  ，              
changed_folder = input("Enter the folder yout want to roll back:
\t\t
")

#    
os.chdir(changed_folder)

#        
os.getcwd()

path = os.getcwd()
#          
dirs = os.listdir(path)
for dir in dirs:
        print(dir)

print("*" * 20)        #        

#     
for dir in dirs:
        old_filename = dir        #              
        print(old_filename)        #    ，      （    ）


        new_filename = old_filename.replace("[vale]-","")   
                         #         replace     ，（    ，    ）
        print(new_filename)


        os.rename(old_filename,new_filename)    #     
#               ，         ，         ，
