I want to rename all upper case letters from file names to lower case letters.

my file structure

p:\TeSt\001-Movie.txt
p:\TeSt\002-moVie.txt
p:\TeSt\003-Pics.txt
p:\TeSt\004-KKKFLfasf.txt

and this is how it should look

p:\TeSt\001-movie.txt
p:\TeSt\002-movie.txt
p:\TeSt\003-pics.txt
p:\TeSt\004-kkkflfasf.txt

However, the folder should not be renamed

import os
path = 'p:\TeSt'
for file in os.listdir():
    os.rename(file, file.lower())
then = os.listdir()

but I get an error and the files are not renamed.

You just need to give the full path of the files and pass that to the rename function, it should work.

Try the below code:

import os

path = 'p:/TeSt/'

for file in os.listdir(path):
    os.rename(path + file, path + file.lower())

then = os.listdir(path)
print(then)

output:

['001-movie.txt', '004-kkkflfasf.txt', '002-movie.txt', '003-pics.txt']

NOTE: Forwadslash (/) has been used in order to avoid using (\) which is a special character in python. You can always replace / with \\ in windows.
