Run the codes from built-in terminal

I just start the complete python mastery course. It is pretty amazing! I run into a problem when I follow the class no. 9 “type conversion” of group 2 primitive types. I use the visual studio 3.9 in a window. When I try to use the terminal (by view and choosing the terminal), I can not run the simple code called “app.py” by typing “$python app.py”. it retuns an error says:
At line:1 char:9

  • $python app.py
  •     ~~~~~~
    

Unexpected token ‘app.py’ in expression or statement.
+ CategoryInfo : ParserError: (:slight_smile: [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : UnexpectedToken

what should I do in order to run the codes properly in the built-in terminal?

Thanks!

Sorry, just check the previous topic and find the proper command is
python app.py

Mosh displays “python app.py" in the class. I though I should add "” before python.

Thanks!
