The Python for Mac OS X installers downloaded from this website dynamically link at runtime to Tcl/Tk Mac OS X frameworks. The Tcl/Tk major version is determined when the installer is created and cannot be overridden. The Python 64-bit/32-bit Mac OS X installers for Python 3.5.x, 3.4.x, 3.3.x, 3.2.x, and 2.7.x dynamically link to Tcl/Tk 8.5. Depends on what you're going to use python for. Things like scripts/back-end APIs should be fine (I'm doing these sort of tasks on my 2015 Air), but anything that involves heavy computation (training a neural net for example), or anything that requires a large amount of compilation will probably be better on the Pro.

You may be a little concerned about the differences between Python 2 and Python 3, so you wantto make sure that you have the latest versions of each available. This will enable you to switchbetween them easily and work on porting Python 2 programs to Python 3.

Which Python Version To Download For Macbook Air 2

OS vendor Python versions lag behind the latest available and can only be updated by installing amajor patch or bolting-on an additional Python installation:

OS Version System Python Version
OSX 10.13 2.7.10
OSX 10.12 2.7.10
OSX 10.11 2.7.10
Ubuntu 16.04 LTS Xenial Xerus 2.7.11
Ubuntu 14.04 LTS Trusty Tahr 2.7.5
Ubuntu 12.04 LTS Precise Pangolin 2.7.3

One way to work around this issue is to use pyenv to install theversions of Python you want to use. This tool provides a simplified build environment for installingthe Pythons you want, while providing a set of shell script shims that makes it easy to switch betweenthem. This tool was inspired by and forked from rbenv andruby-build.

Install Python with pyenv¶

  1. Start a Terminal session.

  2. Install Homebrew and Xcode Command Line Tools.

  3. Install pyenv.

  4. If you already have pyenv installed, you can upgrade it to gain access to the latest Pythonversions. The pyenv tool is updated periodically with new formulas for the latest releases.

  5. Add configuration to your .bash_profile to initialize pyenv every time you start a newTerminal. The PYENV_ROOT, which is where Python versions and packages will be installed,defaults to $HOME/.pyenv.

  6. Load your .bash_profile configuration changes.

  7. List the available Python versions. Notice that you have access to several differentdistributions: python.org (plain version numbers), anaconda, ironpython, jython, miniconda,pypy and stackless. We will install the standard Python versions released bypython.org, otherwise known as CPython, because theinterpreter is written in C.

  8. If you are running OSX 10.13, you will need to set the following environment variables, when youinstall new Python versions. See #988 for more details.

  9. Install Python versions.

  10. List the available Python versions.

  11. Activate a Python version and verify that it is available.

  12. Activate another Python version and verify that it is available.

  13. If desired, activate multiple Python versions and verify that they are available.PEP 394 -- The 'python' Command on Unix-Like Systemsexplains conventions for naming python binaries.

  14. Create new directories for Python projects, add pyenv local version files and verify the Pythonversions. Your python version will automatically switch when you change into these directories.

Useful Python Packages¶

This is a small collecton of useful packages that will help get you started doing useful thingswith Python.

Install flake8, which is a static analyzer that enforcesgood Python coding style and alerts you to coding mistakes. Now that you have Python installed,you can use the pip command to install any additional modules that you want to use. You willneed to install modules separately for each version of Python you are actively using.

Install advanced Python Read-Eval-Print-Loop (REPL) packages, which will make it easier to explorePython code, because they grant access to tab completion and fancy editing capabilities. The ipythontool is a command line REPL, which can be exited with ctrl-d. Jupyter Notebook is a browser-basedREPL that operates on individual cells of code. The IPython Interactive Computingwebsite has more information on these tools.

Install Requests: HTTP for Humans, which makes it easyto consume HTTP services. See GitHub's REST API v3 documentationfor more details on endpoints that are avaialble.

Install Flask: A Python Microframework, which can be used to quickly buildsmall websites that automate everyday tasks.

If you need Python package isolation on a per-project basis, because you have conflicting setsof packages specified for different projects, you can use virtualenvto set up separate environments. The virtualenv tool establishes a clean room Python installation,either based upon the current version of Python in use, or a version specified on the command line.If you have multiple Python versions activated in pyenv, you can use virtualenv to switch betweenthem easily.

Automated Testing with Python¶

While working on Python programs, you may be interested in automating testing. The most commonchoice for implementing this is tox, which willallow you to run tests with multiple different versions of Python, if needed.
