Change the extension of multiple files

Import OS Directory path where files Directory = "/Route/Directory/You" # change this The cycle between the files For Fileneame in os.listdir (Directory): FULL_PATH = os.path.join (Directory, Fileename)

# Only if the file is and the extension is not
if os.path.isfile(full_path) and '.' not in filename:
    new_name = filename + '.pdf'
    new_path = os.path.join(directory, new_name)
    os.rename(full_path, new_path)
    print(f"تغییر نام: {filename} → {new_name}")

Print ("All extensions without extension to pdf change"))

Hi dear friend, steps are that:

1. Enter the directory you want.
2. Click View at the top menu.
3. Click on the Show section.
4. Tick the file name extensions.
5. The extension of all files must be revealed now.
6. You can change both their name and extension now.
