os.path works just as well:

'date'

This code changes the file extension from .txt to .pdf. Learn more about Python Pathlib with_suffix().

Python's pathlib Module: Taming the File System – Real Python
4 days ago - When using .write_text(), Python overwrites any existing files on the same path without giving you any notice. That means you could erase all your hard work with a single keystroke! As always, when you write files with Python, you should be cautious of what your code is doing. The same is true when you’re renaming files. ... When you want to rename files, you can use .with_stem(), .with_suffix(), or .with_name().
