I found a great instruction (https://viddownmadness.com/how-to-download-embedded-vimeo-videos/) how to download embedded vimeo videos and thought it would be a nice project to do this in python.
My first idea was to do this in selenium, but maybe you can point me out a more elegant way?
First step to take is to check if someone did not make it already to avoid so-called reinventing the wheel. Python Package Index is often good place to start, I searched for vimeo and there are many options providing download feature, but I suggest taking vimeo-downloader as it was updated recently (Jun 9, 2021) and packages not updated for long time might not longer work correctly if vimeo changed something in meantime. After reading vimeo-downloader Project description you should be able to install and use it.
