    You should not be learning Python 2 in 2018. By the original timeline, it should be dead already (though it's now in terminal care on an extension for about a year and a half still). The recommended and supported version of the language is Python 3. – tripleee Aug 23 '18 at 14:17

You can use os.rename as long as they are on the same filesystem. Otherwise, use shutil.move

To get the date you can use datetime.datetime.today().strftime("%Y_%m_%d_%H%M%S") and use the output of that in the new name of your file. (see how to use strftime here)

For example:

my_file = 'file_1.pdf'
file_name, file_extension = os.path.splitext(my_file)
date_str = datetime.datetime.today().strftime("%Y_%m_%d_%H%M%S")
os.rename(my_file, file_name + '_' + date_str + file_extension)

Try

import os
import time

current_milli_time = lambda: int(round(time.time() * 1000))

os.rename('3214.xlsx', f'3214_{current_milli_time}.xlsx')
