How To Download Python For Mac
Numerical Python for Mac (NumPy) is a package for scientific computing with Python.It adds a fast and sophisticated array facility to the Python language. NumPy is the most recent and most actively supported package. Numerical Python for Mac contains: A powerful N-dimensional array object. Python is a popular programming language that is widely used by beginners and longtime developers alike. Modern Mac OS versions come with Python 2.7.x installed (or Python 2.6.1 if an older Mac OS X version), but many Python users may need to update Python in Mac OS to a newer version like Python 3.7.x or newer. If you are using a Mac, see the Python for Mac OS X page. MacOS since 10.2 (Jaguar) include a system version of Python, but it is best not to consider this the Python to use for your programming tasks - install a current Python instead. 10.15 (Catalina) is the last MacOS to include a default system Python, as Apple have now deprecated this. The Python 64-bit/32-bit macOS installers for Python 3.6.x and and 2.7.x dynamically link to Tcl/Tk 8.5 frameworks. The dynamically linking occurs when tkinter (Python 3) or Tkinter (Python 2) is first imported (specifically, the internal tkinter C extension module). Sep 10, 2019 This short tutorial will show you how to properly install Python 3 on a Mac OS X computer. There are multiple ways to install Python 3, including a download from the official Python site, however I strongly recommend instead using a package manager like Homebrew to manage all your dependencies going forward. It will make your life a lot simpler. Download Python 3.6 for Mac from our software library for free. Our built-in antivirus scanned this Mac download and rated it as virus free. The file size of the latest downloadable setup file is 26.2 MB. The program belongs to Developer Tools. The most popular versions of the program are 3.3, 2.7 and 2.6.

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 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

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.
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.
