Opening a terminal
Before we install Python, we’ll need to check whether Python is already installed. To do that, we’ll need a terminal. How to open a terminal depends on the system you’re using.
For Linux, depending on your distribution, you can use the shortcut Ctrl + Alt + T. If that doesn’t work, you can open the application menu (sometimes called Activities) and look for the applications. There, you can search for terminal. Click on the terminal icon. That should open the terminal.
For Windows, there are two built-in terminals: the command prompt and PowerShell. Either one of those is fine. You can open the command prompt with the shortcut Windows button + R. Or, you can type cmd in the search box in the start bar.
