For those who are learning Python on a Mac, it may be slightly frustrating that Apple doesn't provide the latest version, typically used when learning Python these days. Here's a short and sweet Q&A session on what you need to know to download and install the latest version of Python (3.4.1).
1. Why is Apple only providing Python 2.x?

Python for Mac 2019 full offline installer setup for Mac Python for Mac is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Miniconda is a free minimal installer for conda. It is a small, bootstrap version of Anaconda that includes only conda, Python, the packages they depend on, and a small number of other useful packages, including pip, zlib and a few others. Use the conda install command to install 720+ additional conda packages from the Anaconda repository.
As the Python website says, 'Python 2.x is legacy, Python 3.x is the present and future of the language.' Briefly, in order to move forward technically as a language, the creator, Guido van Rossum, needed to make some significant internal changes. To do this, backwards compatibility had to be compromised. As a result, the 3.x version can't be depended on to run 2.x scripts.
There are large libraries for Python 2.x and many users still need to use it, so Python 2.7.x is installed in OS X by default. Even OS X 10.10 Yosemite provides Python 2.7.x. So when should you use version 2 and when should you use the latest release, 3.4? The Python.org site says:
Firstly, if you're deploying to an environment you don't control, that may impose a specific version, rather than allowing you a free selection from the available versions.
Secondly, if you want to use a specific third party package or utility that doesn't yet have a released version that is compatible with Python 3, and porting that package is a non-trivial task, you may choose to use Python 2 in order to retain access to that package.
Alternatively, if you're a newbie to the language and/or your class instructor insists that you begin by learning 3.x, then you'll need to install it on your Mac. It's particularly easy to do because 1) There's an OS X installer package that does all the work and 2) You can still run both versions, so there's no penalty to installing 3.x.
2. Where can I get Python 3.x?
Go to the Python website's download page. It should auto-detect that you're on a Mac and offer you some options. You're probably wanting 3.4.1. The interesting part of the page will look something like this:
It's important that you read the file 'ReadMe.txt'. There, you'll discover, along with other things, that you may not be able to just double-click the installer, 'Python.mpkg' because it's not signed by Apple. (Whether you can double-click it will depend on how you have your Gatekeeper settings set in 3. How do I install Python 3 and where does it get installed? If you're using the OS X default setting for Gatekeeper, you'll need to right-click the installer package and select: Like this: Unlike Apple's default install of 2.x, the version 3.x that you're installing goes into your own library folder. Using the symbol ~ as a shorthand for /Users/<your acct name>, then we can write the location as: 4. How do I run Python 3? The installer added the path for the above to your default path in .bash_profile so that when you type: on the command line, the system can find it. You'll know you've been successful if you see the Python interpreter launch. Exit the interpreter with CTRL-D. 5. How do I run the older 2.x versions? If you look at: you'll see that several older 2.x versions are already installed. To get to the latest 2.x version, and that shouldn't change because 2.x isn't being updated anymore, you can, on the command line, type: Alternatively, you can enter the commands python2.5 or python2.6 to get to those older versions if needed. Power iso for mac os x 10.4. 6. Where can I learn more? There is a boatload of friendly information about Python at their website. It's beautifully laid out. 1. Absolute beginner with no experience programming a computer. 'Python Programming' by Michael Dawson. 2. For those who know a little programming. 'Python Programming' by John Zelle. 3. For experienced programmers who want to learn Python. 'Learning Python' by Mark Lutz. This book (5th edition) covers both 2.x and 3.x. This page tells you how to setup a Python programming environment for your Mac OS X computer and provides a step-by-step guide for creating and running a simple 'Hello, world' Python program. All of the software is freely available on the Web. These instructions are for MacOS X 10.13 (High Sierra), but the instructions for other recent versions of Mac OS X are similar. The Python programming environment required by this booksite consists of: Python 2 is bundled with Mac OS X. However, Python 3 is not. We recommend that you download and install Python 3, and use Python 3 exclusively when running programs associated with this booksite. Perform these steps to download and install Python, IDLE, Tkinter, NumPy, and PyGame: Browse to the Python for Mac download page. In the resulting page click on the Download Python 3.6.5 button. Your browser will download the file Using Mac Finder Manager, navigate to your Open a Terminal window. To do that, click on the Spotlight Search icon on the right end of the menu bar. (It has the appearance of a magnifying glass.) In the resulting dialog box, type In the Terminal window issue these commands to install NumPy and PyGame: Perform these steps to test your installation: In the Terminal window issue the If you see that output, then your installation of Python, IDLE, and Tkinter was successful.

Initially the working directory is Issue the Issue the Perform these steps to test your installation of the booksite library: In the Terminal window issue the At the Python At the Python Close the Terminal window. So far you've downloaded and installed all of the software that you'll need. You should perform one more step before creating your first program: configure the IDLE programming environment. Follow these instructions: Open a Terminal window. In the Terminal window issue the command Click on the Python → Preferences.. menu item. Click on the General tab. Click on the Open Edit Window radio button. Click on the Ok button. Close the IDLE window. Close the Terminal window. Having installed Python, the Python standard libraries, IDLE, Tkinter, NumPy, Pygame, and the booksite libraries, and having configured IDLE, you are ready to compose your first Python program. Perform these instructions: Using the Mac Finder, create a directory named Open a Terminal window. Issue the Issue the command In IDLE, type the four-line Python program helloworld.py exactly as it appears below. Use the arrow keys, mouse, or touchpad to move within the text that you have typed. Use the Delete key to delete text. Be careful; the smallest typing mistake might cause the program to fail. When you are finished typing, in IDLE click on the File → Save.. menu item to save the Python program. Save it in a file named The final step is to run your program. It is possible to run some Python programs from within IDLE, but you should run the programs associated with this booksite directly from a Terminal window. To do that, perform these steps: Within the same Terminal window, issue the Issue the Close the IDLE window. Close the Terminal window. You now have installed and configured a reasonable Python environment, and have used it to compose and run a Python program. Congratulations! You are a Python programmer! We recommend that you download the booksite example programs, that is, the example Python programs that are presented incrementally throughout the booksite. Having done so, you can run those programs to help you learn about them. Perform these instructions: Use your Web browser to download this introcs-python.zip file to your In the Mac Finder, double-click on Then perform these steps to test your download of the booksite example programs: Open a Terminal window. Issue the Issue the Issue the Close the stddraw window. Close the Terminal window. We recommend that you download the booksite example data, that is, the data files used by the booksite example programs that are presented incrementally throughout the booksite. Perform these instructions: Use your Web browser to download this introcs-data.zip file to your In the Finder, double-click on Previously on this page we described how to download and install the booksite library so Python can find it. Now we describe how to download the booksite library so you can find it — for the sake of studying the code that implements it, should you so desire. Perform these instructions: Use your Web browser to download this stdlib-python.zip file to your In the Mac Finder, double-click on We invite you to study the code that implements the booksite library. But don't be concerned if some of the code is cryptic. The code that implements the booksite library uses some features of Python that are beyond the scope of the textbook and this booksite. Q. Why do I get the error A. You must issue the command Q. I downloaded files using my browser, but can't find them. Where are they? A. Many browsers by default place downloaded files in the directory Q. How do I break out of an infinite loop when running my program from the Terminal application? A. Type Ctrl-c. That is, while pressing the Ctrl key, type the c key. Q. Must I use IDLE to create my Python programs? Can I use some other text editor? A. You need not use IDLE to create your Python programs; it is fine to use some other text editor. For example, it is reasonable to use the TextEdit editor that is bundled with Mac OS X. However if you do use some other text editor, then make sure you change its settings so it (1) uses a four-space indentation scheme, and (2) indents using spaces instead of tabs. The Wikipedia Comparison of text editors page provides summary descriptions of many text editors.
Overview
Downloading and Installing Python, IDLE, Tkinter, NumPy, and Pygame
Note: The Mac Finder application uses the term folder to mean a container of documents and, perhaps, other folders. This document instead uses the equivalent Unix term directory. python-3.6.5-macosx10.6.pkg to your DownloadsDvd burner software for mac. directory.Downloads directory, and double-click on the python-3.6.5-macosx10.6.pkg file to install Python, Tkinter, and IDLE. Use the default options. (It's OK to delete the python-3.6.5-macosx10.6.pkg file after the installation is complete.)Terminal.app followed by the Enter key.To 'issue a command' you should type the command followed by the Enter key. python3 command. You should see something like this:>>> prompt, type import numpy followed by the Enter key. If no error messages appear, then your installation of NumPy was successful.>>> prompt, type import pygame followed by the Enter key. If no error messages appear, then your installation of PyGame was successful.>>> prompt, type exit() followed by the Enter key to exit Python.idle3. If an IDLE window appears, then you have installed IDLE properly. Close the IDLE window.IMPORTANT: When running the Python programs associated with this booksite, do not issue the python command. Instead issue the python3 command. The former command runs the Python 2 compiler/interpreter that is bundled with Mac OS X; the latter command runs the Python 3 compiler/interpreter that you installed by following the instructons on this page.Downloading and Installing the Booksite Library
/Users/yourusername/Downloads directory./Users/yourusername/Downloads/introcs-1.0.zip to unzip the file, thus creating a directory named /Users/yourusername/Downloads/introcs-1.0. (It's OK to delete the /Users/yourusername/Downloads/introcs-1.0.zip file after you have unzipped it.)/Users/yourusername. In the Terminal window issue the cd Downloads command to change your working directory to /Users/yourusername/Downloads, and then issue the cd introcs-1.0 command to change your working directory to /Users/yourusername/Downloads/introcs-1.0. (Incidentally, the cd . command changes your working directory to the 'parent' of the current working directory.)ls command to display the names of all files in your working directory. Make sure that a file named setup.py is in your working directory.python3 setup.py install --user command. The computer copies the files defining the booksite modules to a directory where Python can find them, and writes status messages to your Terminal window to indicate its progress.Install Python 3.6 For Mac
python3 command.>>> prompt, type the statement import stdio followed by the Enter key. If Python generates no error messages, then you have installed the booksite library properly.>>> prompt, type exit() followed by the Enter key to exit Python.Configuring IDLE

Python On The Mac
/Users/yourusername/hello.cd hello command to make the /Users/yourusername/hello directory your working directory.idle3 & to launch IDLE. Note the trailing ampersand. The trailing ampersand tells the computer to run the idle3 program in the background, thereby leaving your Terminal application free to handle additional commands while IDLE is running.helloworld.py in the directory /Users/yourusername/hello. The file name is case sensitive, so make sure you use all lowercase letters.Running Your First Program
ls command to display the names of all files in the working directory. Confirm that the working directory contains your helloworld.py file.python3 helloworld.py command to run your program. If the computer writes 'Hello, World' to the Terminal window, then the execution of your helloworld.py program was successful. If the computer instead writes error messages, then use IDLE to correct your program, and issue the python3 helloworld.py command again. Repeat until your program runs successfully. If your program runs successfully the first time you try, then intentionally introduce an error into your program, just so you get some experience with correcting errors.Downloading the Booksite Example Programs (optional)
/Users/yourusername/Downloads directory./Users/yourusername/Downloads/introcs-python.zip to unzip the file, thus creating the /Users/yourusername/Downloads/introcs-python directory containing the booksite example programs. (It's OK to delete the /Users/yourusername/Downloads/introcs-python.zip file after you have unzipped it.)cd Downloads and cd introcs-python commands to make /Users/yourusername/Downloads/introcs-python your working directory.ls command. Confirm that the working directory contains a file named bouncingball.py.python3 bouncingball.py command. If Python launches a stddraw window showing an animated bouncing ball, then your download of the booksite example programs was successful.Downloading the Booksite Example Data (optional)
/Users/yourusername/Downloads directory./Users/yourusername/Downloads/introcs-data.zip to unzip the file, thus creating the /Users/yourusername/Downloads/introcs-data directory containing the booksite example data files.
