OneDrive files, photos and photo albums
Have not had the time to properly document or pipify it, but onedriver will handle the authentication and give you access to your files, including the photo albums using an undocumented API.
I wrote this instead of using the Microsoft API Python library, because it made the auth complicated and did not provide access to the photo albums, where our family has years of nicely organized photos.
Also, I found this a convenient way of removing a bunch of duplicates I had on OneDrive.
I use it with Pythonista, but works anywhere with Python 3.6+ and a web browser.
