Rename Files based on XML file

[klturi421]

os.listdir() dos not return absolute path,so will get problem(file not found) if not is same folder when try to rename.
A trick can be to add line-8,so it change to this folder:

os.chdir('./06-27-2021')

Or join so using absolute path:

os.rename(os.path.join(path, scr), os.path.join(path, dst))

That's exactly what I was missing. I didn't realize that it was not calling to the right folder to run and made so much more sense once I read your reply. Thank you!
