How can I rename all files in a folder with names from a text file?
Suppose I have a inventory.txt with the contents:

list-item1.ext

list-item2.ext

And there are files in a folder Downloads called:

file1.ext

file2.ext

So the new file names should be:

file1.ext    >>>  list-item1.ext

file2.ext    >>>  list-item2.ext

Thanks!

Here is updated code:

import os



path="c:\Users\dimai\Downloads"

files = os.listdir(path)

filename="c:/Users/dimai/Documents/inventory.txt"

print("Current File list:")

print(files)



with open(filename) as f:

    mylist = f.read().splitlines()

print("Items from txt file:")

print(mylist)



str2 = ' '.join(mylist)



i = 1

for file in files:

    os.rename(os.path.join(path, file), os.path.join(path, str2))

    i = i+1

Output:

Traceback (most recent call last):

  File "C:UsersdimaiOneDriveBackupsPythonvideo-rename-0.2.py", line 18, in <module>

    os.rename(os.path.join(path, file), os.path.join(path, str2))

FileExistsError: [WinError 183] Cannot create a file when that file already     exists:: 'c:\Users\dimai\Downloads\file2.mp3' ->     'c:\Users\dimai\Downloads\list-item1.ext list-item2.ext'

So file1.ext was renamed to list-item1.ext list-item2.ext
and file2.ext was not renamed at all.

Python os library has all the things you need here. Look into listdir and rename.

Use readlines function - it gives you all the lines in the file in a list. Listdir also returns a list with actual file names. Check if the lists are same size then loop and rename. Don forget to append path to the file names as well

I've tried to do that, but now I got syntax incorrect error. If there is only one file in folder - it will be renamed without any errors.
