How to install Python on Mac OS and How to write and execute or run your first Python program on Mac OS will be covered in this video.We start by installing.

Python on a Mac running macOS is in principle very similar to Python onany other Unix platform, but there are a number of additional features such asthe IDE and the Package Manager that are worth pointing out.

  • Install Python 3.8 Mac Terminal Commands Distutils based source distributions¶ If you download a module source distribution, you can tell pretty quickly if itwas packaged and distributed in the standard way, i.e. Using the Distutils.First, the distribution’s name and version number will be featured prominentlyin the name of the downloaded.
  • Doing it Right¶. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package.

5.1. Getting and Installing MacPython¶

macOS since version 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, youare invited to install the most recent version of Python 3 from the Pythonwebsite (https://www.python.org). A current “universal binary” build of Python,which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is availablethere.

What you get after installing is a number of things:

  • A Python3.9 folder in your Applications folder. In hereyou find IDLE, the development environment that is a standard part of officialPython distributions; and PythonLauncher, which handles double-clicking Pythonscripts from the Finder.

  • A framework /Library/Frameworks/Python.framework, which includes thePython executable and libraries. The installer adds this location to your shellpath. To uninstall MacPython, you can simply remove these three things. Asymlink to the Python executable is placed in /usr/local/bin/.

The Apple-provided build of Python is installed in/System/Library/Frameworks/Python.framework and /usr/bin/python,respectively. You should never modify or delete these, as they areApple-controlled and are used by Apple- or third-party software. Remember thatif you choose to install a newer Python version from python.org, you will havetwo different but functional Python installations on your computer, so it willbe important that your paths and usages are consistent with what you want to do.

IDLE includes a help menu that allows you to access Python documentation. If youare completely new to Python you should start reading the tutorial introductionin that document.

If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.

5.1.1. How to run a Python script¶

Your best way to get started with Python on macOS is through the IDLEintegrated development environment, see section The IDE and use the Help menuwhen the IDE is running.

Terminal

If you want to run Python scripts from the Terminal window command line or fromthe Finder you first need an editor to create your script. macOS comes with anumber of standard Unix command line editors, vim andemacs among them. If you want a more Mac-like editor,BBEdit or TextWrangler from Bare Bones Software (seehttp://www.barebones.com/products/bbedit/index.html) are good choices, as isTextMate (see https://macromates.com/). Other editors includeGvim (http://macvim-dev.github.io/macvim/) and Aquamacs(http://aquamacs.org/).

To run your script from the Terminal window you must make sure that/usr/local/bin is in your shell search path.

To run your script from the Finder you have two options:

  • Drag it to PythonLauncher

  • Select PythonLauncher as the default application to open yourscript (or any .py script) through the finder Info window and double-click it.PythonLauncher has various preferences to control how your script islaunched. Option-dragging allows you to change these for one invocation, or useits Preferences menu to change things globally.

5.1.2. Running scripts with a GUI¶

With older versions of Python, there is one macOS quirk that you need to beaware of: programs that talk to the Aqua window manager (in other words,anything that has a GUI) need to be run in a special way. Use pythonwinstead of python to start such scripts.

With Python 3.9, you can use either python or pythonw.

5.1.3. Configuration¶

Python on macOS honors all standard Unix environment variables such asPYTHONPATH, but setting these variables for programs started from theFinder is non-standard as the Finder does not read your .profile or.cshrc at startup. You need to create a file~/.MacOSX/environment.plist. See Apple’s Technical Document QA1067 fordetails.

For more information on installation Python packages in MacPython, see sectionInstalling Additional Python Packages.

5.2. The IDE¶

MacPython ships with the standard IDLE development environment. A goodintroduction to using IDLE can be found athttp://www.hashcollision.org/hkn/python/idle_intro/index.html.

5.3. Installing Additional Python Packages¶

There are several methods to install additional Python packages:

  • Packages can be installed via the standard Python distutils mode (pythonsetup.pyinstall).

  • Many packages can also be installed via the setuptools extensionor pip wrapper, see https://pip.pypa.io/.

5.4. GUI Programming on the Mac¶

There are several options for building GUI applications on the Mac with Python.

PyObjC is a Python binding to Apple’s Objective-C/Cocoa framework, which isthe foundation of most modern Mac development. Information on PyObjC isavailable from https://pypi.org/project/pyobjc/.

The standard Python GUI toolkit is tkinter, based on the cross-platformTk toolkit (https://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttps://www.activestate.com; it can also be built from source.

Install

wxPython is another popular cross-platform GUI toolkit that runs natively onmacOS. Packages and documentation are available from https://www.wxpython.org.

PyQt is another popular cross-platform GUI toolkit that runs natively onmacOS. More information can be found athttps://riverbankcomputing.com/software/pyqt/intro.

5.5. Distributing Python Applications on the Mac¶

The standard tool for deploying standalone Python applications on the Mac ispy2app. More information on installing and using py2app can be foundat http://undefined.org/python/#py2app.

5.6. Other Resources¶

The MacPython mailing list is an excellent support resource for Python users anddevelopers on the Mac:

Another useful resource is the MacPython wiki:

Introduction

Python is a high level, dynamic, general purpose language. It was developed by Guido Van Rossum in 1991. Python's syntax allows developers to use fewer lines of code than any other programming language. It basically focuses on the code readability of program. Python 2.7 is installed by default on MacOS but we can install other versions like python 3.5 and 3.6.

In this tutorial, we are learning how to install Python 3.6.3 on the MAC Operating system.

Prerequisites

  • MacOS
  • Login as an administrator on terminal

Installation

There are following steps which are used while installing Python3 on MacOS.

1) Checking python's version on the system

We can check which version of the Python is currently installed on our system. Generally, Python 2.7 is installed by default.

Let's see how can we do it.

Install Python 3.8 Mac Terminal

It shows Python 2.7.10 is installed on the computer which is quite often.

2) Download Python 3.6.3

In order to install Python 3.6.3, we must download the latest version from its official website https://www.python.org/downloads/ . The file is downloaded in .pkg format which can be directly installed by using Installer command.

3) Install Python 3.6.3

Since the downloaded file already is in .pkg format hence no mounting is required and We can use installer command to install Python 3.6.3.

Let's see how can we do it.

Since The installer is used with super user permissions hence sudo forces terminal to prompt the user to fill the admin password. The process installs the Python 3.6.3 to the root directory which is mentioned with the target option.

4) Verify Python3

To check which Python version is installed on the machine, we can use python -version command. Since by default installed version is Python 2.7.10 hence it shows python 2.7.10. but it gives us flexibility to check the version of Python 3 on our computer.

Let's see how can we use python 3 to check which version of python 3 is running.

5) Working on Python's script mode

To work on Python command line, we simply type python3 on the terminal. Python shell open where we can run Python statements such as print statements as we did here.

To run a Python file (.py) on the terminal, we simply type the file name and the file will be interpreted.
