Let's click on continue to walk our way through the wizard. Once it's finished downloading, you can go ahead and double click the file to open it up. And since this is newer than what we have installed on our Mac, let's go ahead and download it. In this case, Python three dot seven dot three is the latest version. Here, you can see the latest version of Python that's available for your operating system.
If for some reason you don't see the version of Python that's installed, or you're not sure if you're running the latest version of Python, you can head over to /downloads. We can do this by typing exit, and then a open and closed parentheses and hitting Enter. But for now, we're just going to go ahead and exit. This is letting us know that the computer is ready for us to send it some Python instructions. This is denoted by the three angle brackets.

From here, we can check what version of Python we have installed. Let's go ahead and close down our Finder window. You can also do this with a shortcut by typing command + space, and then spelling out terminal and hitting Enter. To open up Terminal, we're going to go to our Finder, then applications. Terminal is an application that lets you run commands to explore directories, execute scripts, and yes, work with Python. To check what version of Python is installed, we're going to open a Terminal window. If you're using Windows, please skip to the next video, as I'll walk you through how to get set up.
