How to Install Python on Your Computer
Whether you use a Mac, Windows, or Linux OS (operating system), you can find and install Python on your computer. The following sections give you instructions for each OS.
How to install Python on Mac OSX
To find and start Python on Mac OSX computers, follow these steps:
Press Cmd+spacebar to open Spotlight.
Type the word terminal.
Or, from the Finder, select Finder→Go→Utilities→Terminal.
The Terminal window opens.
In the terminal, type python.
The Python interpreter that’s built in to Mac OSX opens.
How to install Python on Windows
Unfortunately, Python doesn’t come on Windows. If you’re running Windows, then you need to download and install Python by following the instructions here. Installing Python on Windows isn’t difficult. If you can download a file from a website, you have the skills to install Python.
Fortunately, the Python Foundation (the peeps who guide the development of Python) makes installable files available from its website.
Firefox and Internet Explorer responded differently to the Python download website, so the instructions are based on which of these browsers you use. If you use a whole other browser altogether, try the Internet Explorer instructions.
Installing with Firefox
To install Python on a Windows machine with Firefox, follow these steps:
Click the button that says Download Python 2.7.9.
Or, if it’s there, click a more recent version number that starts with 2.7.
Clicking this button automatically downloads and saves an msi file for you. If not, try the instructions for Internet Explorer. See Figure 1.
