Execute python script from web applicaton

I am currently working on a personal project in Python, especially in Flask. The goal is to create an web application, which would be able to execute python, or its framework scripts from the web page.

I am quite beginner to this area and I am trying to figure out, is there any way, to execute the script(s) on the server side so only output would be displayed afterwards or could you recommend me some resources?

Thank you all if you deal with this question.
