Before you download and install Python on your computer, you might want to check if you already have it. Depending on your operating system, you might have a pre-installed version of Python on your computer. However, this version might not be the latest one or the one you need for your projects. To check if you have Python on your computer and what version it is, you can use the following methods:
Windows users can use PowerShell, cmd.exe, or Windows Terminal to check their Python version
If you are using Windows, you can use one of the following tools to check your Python version:
PowerShell: PowerShell is a command-line shell and scripting language that comes with Windows. To open PowerShell, you can press the Windows key + X and select Windows PowerShell from the menu. Alternatively, you can type PowerShell in the search box and click on the app. To check your Python version in PowerShell, you can type python --version or py --version and press Enter. If you have Python on your computer, you will see the version number displayed. If not, you will see an error message saying that python or py is not recognized as a command.
cmd.exe: cmd.exe is the default command-line interpreter for Windows. To open cmd.exe, you can press the Windows key + R and type cmd in the Run dialog box. Alternatively, you can type cmd in the search box and click on the app. To check your Python version in cmd.exe, you can type python --version or py --version and press Enter. If you have Python on your computer, you will see the version number displayed. If not, you will see an error message saying that python or py is not recognized as a command.
Windows Terminal: Windows Terminal is a modern terminal application that allows you to access multiple command-line tools in one window. To open Windows Terminal, you can press the Windows key + X and select Windows Terminal from the menu. Alternatively, you can type Windows Terminal in the search box and click on the app. To check your Python version in Windows Terminal, you can select PowerShell or cmd.exe from the drop-down menu at the top of the window. Then, you can type python --version or py --version and press Enter. If you have Python on your computer, you will see the version number displayed. If not, you will see an error message saying that python or py is not recognized as a command.
macOS users can use Terminal to check their Python version
If you are using macOS, you can use Terminal to check your Python version. Terminal is a command-line interface that comes with macOS. To open Terminal, you can go to Applications > Utilities > Terminal. Alternatively, you can press Command + Space and type Terminal in the Spotlight search box.
