Mac OS X comes with Python 2.7 out of the box. Now, we can install Python 2.7: $ brew install python@2. Setuptools enables you to download and install any compliant Python software over a network (usually the Internet) with a single command (easyinstall). It also enables you to add this network installation capability to your own Python. Download the latest version of PyCharm for Windows, macOS or Linux.
Python 2.7.2
Note: A newer bugfix release, 2.7.3, is currently available. Its use is recommended over Python 2.7.2.
Python 2.7.2 was released on June 11th, 2011.
The Python 2.7 series is scheduled to be the last major version in the 2.xseries before 2.x moves into an extended maintenance period. The 2.7 seriescontains many of the features that were first released in Python 3.1.Improvements in this release include:

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 The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Doing it Right¶
Let’s install a real version of Python.
Python 2.7 Mac Download Version
Before installing Python, you’ll need to install a C compiler. The fastest wayis to install the Xcode Command Line Tools by running
xcode-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 .
Setuptools & Pip¶
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.
Virtual Environments¶
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.
