• If you want to get stuck with some simple interpreter experimentation, run python in your terminal to open the REPL.
• If you want to write some serious code, create a file in your workspace (i.e. main.py) and to execute it type python main.py in your terminal.
• Or if you're not a knave and actually want to follow this tutorial, open up the first folder with your code editor.
