Create and deploy scalable, performant apps using.NET and C# on the Mac.
Jobs Programming & related technical career opportunities. I am using OS X El Capitan and my default Python version is 2.7.10. Installing Python on Mac OS X. With older versions of Python, there is one Mac OS X quirk that you need to be aware of: programs that talk to the Aqua window manager (in other words, anything that has a GUI) need to be run in a special way. Use pythonw instead of python to start such scripts. With Python 3.3, you can use either python or pythonw.
All modern Macintosh computers use the Intel chip (like most Windows PCs). Older Macs used PowerPC chips. You don't need to understand the difference, because there's just one Mac Python installer for all Macs.
Visit python.org/download/ and download the Mac installer. It will be called something like Python 3.1 Mac Installer Disk Image, although the version number may vary. Be sure to download version 3.x, not 2.x.
Your browser should automatically mount the disk image and open a Finder window to show you the contents. (If this doesn't happen, you'll need to find the disk image in your downloads folder and double-click to mount it. It will be named something like python-3.1.dmg.) The disk image contains a number of text files (Build.txt, License.txt, ReadMe.txt), and the actual installer package, Python.mpkg.
Double-click the Python.mpkg installer package to launch the Mac Python installer.
The first page of the installer gives a brief description of Python itself, then refers you to the ReadMe.txt file (which you didn't read, did you?) for more details.

Like all good installers, the Python installer displays the software license agreement. Python is open source, and its license is approved by the Open Source Initiative. Python has had a number of owners and sponsors throughout its history, each of which has left its mark on the software license. But the end result is this: Python is open source, and you may use it on any platform, for any purpose, without fee or obligation of reciprocity.
Due to quirks in the standard Apple installer framework, you must 'agree' to the software license in order to complete the installation. Since Python is open source, you are really

The next screen allows you to change your install location. You must install Python on your boot drive, but due to limitations of the installer, it does not enforce this. In truth, I have never had the need to change the install location.
From this screen, you can also customize the installation to exclude certain features. If you want to do this, click the Customize button;otherwise click the Install button.
If you choose a Custom Install, the installer will present you with the following list of features:
Framework. This is the guts of Python, and is both selected and disabled because it must be installed.
◦ GUI Applications includes IDLE, the graphical Python Shell which you will use throughout this book. I strongly recommend keeping this option selected.
◦ UNIX command-line tools includes the command-line python3 application. I strongly recommend keeping this option, too.
◦ Python Documentation contains much of the information on docs.python.org. Recommended if you are on dialup or have limited Internet access.
◦ Shell profile updater controls whether to update your shell profile (used in Terminal.app) to ensure that this version of Python is on the search path of your shell. You probably don't need to change this.
◦ Fix system Python should not be changed. (It tells your Mac to use Python 3 as the default Python for all scripts, including built-in system scripts from Apple. Google chrome 52. This would be very bad, since most of those scripts are written for Python 2, and they would fail to run properly under Python 3.)
Click the Install button to continue.
Because it installs system-wide frameworks and binaries in /usr/ local/bin/, the installer will ask you for an
administrative password. There is no way to install Mac Python without administrator privileges.
Click the OK button to begin the installation.
The installer will display a progress meter while it installs the features you've selected.
Assuming all went well, the installer will give you a big green checkmark to tell you that the installation completed successfully.
Click the Close button to exit the installer.
Assuming you didn't change the install location, you can find the newly installed files in the Python 3.1 folder within your /Applications folder. The most important piece is IDLE, the graphical Python Shell.
Double-click IDLE to launch the Python Shell.
The Python Shell is where you will spend most of your time exploring Python. Examples throughout this book will assume that you can find your way into the Python Shell.
