Using Int. Terminal, syntax error

In 6-Using the Integrated Terminal in VS Code

I typed $python manage.py runserver, into the terminal but I am getting the syntax error

File “manage.py”, line 17
) from exc
^
SyntaxError: invalid syntax

I tried closing the terminal window, like Mosh said, but I can’t get it to start the development server.

Who can help resolve this for me? TIA
