Running your first Python program
In order to run our program, we’re going to need the terminal again. So, let’s open the terminal as a first step. We have an additional challenge before we can run it: we need to find the file. Let’s start by asking ourselves the question, where is the file saved? Let’s say that, on my laptop (macOS), it’s stored here:
/Users/zia/Documents/pythoncourse

The easiest way to go there is by entering the full (absolute) path in the terminal, like this:
cd /Users/zia/Documents/pythoncourse
Let’s make sure we’re in the correct folder by asking where we are:
pwd
If you want to see the files that are in there, you can run the dir command for Windows and the ls command for macOS and Linux.
Now that we’re in the correct location, we’ll run the program. We do this by typing the python command, this time not followed by --version, but by the name of the file. So please...
