Programming languages like Python are interpreted. That means the code does not get executed by itself. It needs to be run by another program - called an Interpreter
But first we need to install them. There are lots of python interpreters you can get. You will need to add the Python development environment to your computer.
I like to use Idle - which gets downloaded when you install python from the Internet
For example if you are running on a Windows 11 machine you can download it from from the Microsoft store.
