yea I guess you're right. I should probably seek them indiviually

it's three function calls. language-wise there's nothing difficult in it! look up what the individual things do, and see if you can then explain why it does what it does. if not, then look at the return values from each call to identify where it's behaving differently from what you expected and then you'll at least know which of them to ask about.

Of course clever, but too difficult for me to underestad.

chatGPT answer maybe

I think this is a really clever solution but not a best practice because it is not imediatly apparent how it works. Following zen of python rules 'explicit is better than implicit'
