Javascript Node.js vs Python Flask, making a website [closed]

I’m an IT student and to pass my 3rd year i have to make a project based on business application.
I want to create a website that will allow for hotel service, i.e. accepting reservations, handling orders and tasks. Therefore, I am wondering which technologies I should use. In the classes I dealt with the older version of node.js, but reading articles on the Internet I often see that Flask is mentioned as an easier and more pleasant way of creating websites. Any opinions on these technologies? Or maybe other suggestions?

I was using old version of node.js and i was reading some articles about flask and both have their own advantages etc
