I'm more or less new to computer science and can not even manage to run my first "Hello World" in Flask (Python 3; on my Windows-10 computer). I have tried some different tutorials on how to get started with Flask but did not find them really helpful so I did not finish them. Eventually I found a tutorial that seemed comprehensive and fitting my needs, but Visual Studio Code Terminal could not execute my code but gave me back an Error Message. Maybe I created a global virtual environment before I started this course that I'm following along now, and that's why it gives me that Error, but am not sure. So this is the tutorial that I eventually picked and am currently following along: [this video] .
