For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms. This video explains how to install Python 3 in a Mac OS X, both Mavericks and Yosemite. As the Python website says, 'Python 2.x is legacy, Python 3.x is the. In this video how to install Python 3.8 in a Mac OS X or MacOS, both macOS Catalina. As the Python website says, 'Python 3.x is the present and future of the. Release Date: Nov. Note: A newer bugfix release, 3.3.5, is currently available. Its use is recommended. Python 3.3.3 was released on November 17th, 2013. This release fixes several security issues and various other bugs found in Python 3.3.2. This release fully supports OS X.
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 The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Doing it Right¶
Let’s install a real version of Python.
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.
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.
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

Now, we can install Python 2.7:

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
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_installin 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.

Install TensorFlow 2
TensorFlow is tested and supported on the following 64-bit systems:

No install necessary—run the TensorFlow tutorials directly in the browser with Colaboratory, a Google research project created to help disseminate machine learning education and research. It's a Jupyter notebook environment that requires no setup to use and runs entirely in the cloud. Read the blog post.
