Python for Mac OS X. Python comes pre-installed on Mac OS X so it is easy to start using. However, to take advantage of the latest versions of Python, you will need to download and install newer versions alongside the system ones. The easiest way to do that is to install one of the binary installers for OS X from the Python Download page. Downloads Mac OS X; Python Releases for Mac OS X. Latest Python 3 Release - Python 3.9.0; Latest Python 2 Release - Python 2.7.18; Stable Releases. Python 3.9.0 - Oct. Download macOS 64-bit installer; Python 3.8.6 - Sept. Download macOS 64-bit installer. There are now newer bugfix releases of Python 3.7 that supersede 3.7.0 and Python 3.8 is now the latest feature release of Python 3.Get the latest releases of 3.7.x and 3.8.x here.We plan to continue to provide bugfix releases for 3.7.x until mid 2020 and security fixes until mid 2023. Among the major new features in Python 3.7 are. Python 3.8 is now the latest feature release series of Python 3.Get the latest release of 3.8.x here.Python 3.7.8 was the last bugfix release for 3.7. Python 3.7 is now in the security fix phase of its life cycle. Only security-related issues are accepted and addressed during this phase.

Mac OS X comes with Python 2.7 out of the box.

You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.

The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

Doing it Right¶

Let’s install a real version of Python.

Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.

Note

If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note

If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.

While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run

The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file

If you have OS X 10.12 (Sierra) or older use this line instead

Now, we can install Python 3:

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

will launch the Homebrew-installed Python 3 interpreter.

will launch the Homebrew-installed Python 2 interpreter (if any).

will launch the Homebrew-installed Python 3 interpreter.

If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.

The rest of the guide will assume that python references Python 3.

Pipenv & Virtual Environments¶

The next step is to install Pipenv, so you can install dependencies and manage virtual environments.

A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.

For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.

So, onward! To the Pipenv & Virtual Environments docs!

Feeling brave? Don't mind reporting bugs? Enjoy giving feedback? Then we'd love you to take a sneak peak at the (unfinished work in progress) next version of Mu. These are unsigned installers:

If you're using Mu at EuroPython's beginners' day, this is the version you should install.

There are many ways to install Mu. The simplest is to download the officialinstaller for Windows or Mac OSX. If you find you cannot install Mu because thecomputer you are using is locked down, you should try out PortaMu: a method ofrunning Mu from a pendrive on Windows or OSX. You can also usePython’s built-in pip tool. Some Linux distributions come with Mu packagedalready (and you should use your OS’s package manager to install it). Finally,if you’re on Raspbian (the version of Linux for Raspberry Pi) you can installMu as a package.

If you’re a developer, you can find the source codeon GitHub.

On Linux, in order for Mu to work with the MicroPython based devices you need to ensure you add yourself to the correct permissions group (usually the dialout or uucp groups). Also make sure that your distribution automatically mounts flash devices, or make sure to mount them manually.
