Python Mastery Course (Type Conversion) Part 1

HELP. I am stuck in the type conversion lesson of The Python Mastery course, which I suspect may have something to do with Code Runner or how I am using Terminal. Please look at the embedded screenshot and advise. I am trying to recreate the error as shown in the video screenshot of the lesson. First of all, i was not allowed to enter a value from the terminal (something about read only). Secondly, when I run the code using the $python app.py on mac, it tells me that the code is already running. I also don’t understand why I have to see the long path harlanreece@Harlans-MacBook-Air PythonDemo % in my terminal window, when all I see in Mosh’s terminal window (from video) is Hello World. I have been viewing the results of code output from the output tab in the terminal, which has been working fine. My questions are: Why can’t I recreate the error and did I make a configuration error when I set up Python to run in VS Code and why is long path showing up my terminal window?


I am extremely frustrated as this seems like an important aspect of learning Python. I will submit an additional post with the same question, but different image due to the media posting liimitation.
