title: Why is python3 is not working in command prompt when my python version is 3.9?
body: <p>While running the python file in cmd I have tried python filename and python filename. It works only with python filename. I have python version 3.9 and have added the path as well. I would therefore like to know what is causing the issue. Is it because I have two versions and version 2.7 is overruling version 3.9?</p>
