Note
Check out our guide for installing Python 3 on OS X.
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. Having saidthat, I would strongly recommend that you install the tools and librariesdescribed in the next section before you start building Python applications forreal-world use. In particular, you should always install Setuptools, as it makesit much easier for you to install and manage other third-party Python libraries.
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 The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Let’s install a real version of Python.
Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. Find games for macOS like Friday Night Funkin', Cold Shot, Wrong Floor, Deepest Sword, Dying of Thirst on itch.io, the indie game hosting marketplace. Pyro Mac: 0 ships destroyed and 7 ships lost. Each block represents an hour of the day for each day of the week. The number indicates how many kills were achieved in that hour over the last 90 days. Listen to our Managing Director, Alistair Hackett, give a complete guide to the different types of marine pyrotechnic available on the market today.
Before installing Python, you’ll need to install a C compiler. The fastest wayis to install the Xcode Command Line Tools by runningxcode-select--install
. You can also download the full version ofXcode from the Mac App Store, or theminimal but unofficialOSX-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 decent 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
Now, we can install Python 2.7:
Because python@2
is a “keg”, we need to update our PATH
again, to point at our new installation:
Homebrew names the executable python2
so that you can still run the system Python via the executable python
.
Homebrew installs Setuptools and pip
for you.
Setuptools enables you to download and install any compliant Pythonsoftware over a network (usually the Internet) with a single command(easy_install
). It also enables you to add this network installationcapability to your own Python software with very little work.
pip
is a tool for easily installing and managing Python packages,that is recommended over easy_install
. It is superior to easy_install
in several ways,and is actively maintained.
A Virtual Environment (commonly referred to as a ‘virtualenv’) 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.
To start using this and see more information: Virtual Environments docs.
