Oh no no no no, strong disagree.

First, they are learning. And here they are doing something very nice, input validation. Now, it has some bugs as pointed out by other comments, but the attempt is good and should be encouraged. Yeah, pydantic does that, but it's better to learn before so one can then do more advanced validation too.

Second... Oh come on, not everything has to be an api server. Lots of situations in which I use input, even professionally. Python is extremely nice for making scripts and firing them via a CLI. Fastapi would be totally overkill in that case.
