      Python shell on mac os x bert.heymans at gmail. Mar 15, 2007, 2:56 PM Post #1 of 9 (1985 views). The download instructions seem to steer Mac users to version 2.4.4. Download PyLine - Open Source Python Shell for free. PyLine is a shell that is designed for users who want a easier alternative to cmd, but it is in its earlier stages, so it may not have as many commands. Works on Linux and Windows, and may work on Mac. To install or upgrade pip, download get-pip.py from the official site Then run the following command: sudo python get-pip.py and it will install the pip for your python version which runs the script. – doru Jan 3 '16 at 4:53.

      Python on a Macintosh running Mac OS X 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.

      There are now newer security-fix releases of Python 3.6 that supersede 3.6.6 and Python 3.8 is now the latest feature release of Python 3.Get the latest releases of 3.6.x and 3.8.x here.Python 3.6.8 is planned to be the last bugfix release for 3.6.x. Following the release of 3.6.8, we plan to provide security fixes for Python 3.6 as needed through 2021, five years following its initial. From here, you can double-click IDLE to launch the Python Shell, or click the Close button to exit the package manager. You can always relaunch the Python Shell by going to your Applications menu, then the Programming submenu, and selecting IDLE. The Python Shell is where you will spend most of your time exploring Python.

      4.1. Getting and Installing MacPython¶

      Mac OS X 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.

      4.1.1. How to run a Python script¶

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

      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. Mac OS X 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: Fonelab for mac.

      • 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.

      4.1.2. Running scripts with a GUI¶

      With older versions of Python, there is one Mac OS X 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.

      Download

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

      4.1.3. Configuration¶

      Python on OS X 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.

      4.2. 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.

      4.3. 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/.

      4.4. GUI Programming on the Mac¶

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

      Python For Mac

      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.

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

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

      4.5. 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.

      4.6. 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:

      Check out the steps below to install Python 3 on Mac OSX.

      How to download Python3

      You can download Python 3 by downloading from official Python website or using Homebrew package manager for macOS .

      1) Open up Python official download site. It looks something like the image below. Press Download Python 3.7.4 or the version you would like to download.

      2) After downloading the installer, open it to install Python 3.

      Python 3.7.4 installer Read Me contains the following note about Python 3 and Python 2 Co-existence. Thus, to run Python 3, you can run Python3 or Python3.X.X (a specific version that you installed on your machine). To run Python 2, you can run Python or Python2.7.

      3) Remove Python installer when you are done installing

      4) Run python3 --version to check if Python 3 is installed.

      If you install Python 3.7.X, you can also check its version using this command:

      Homebrew

      Another way to install Python 3 on Mac OS is using Homebrew package manager.

      1) If you don’t have Homebrew install, you can install Homebrew by following the steps on Homebrew site. You can also use the following command to install Homebrew by copy and pasting it onto your terminal.

      2) To install the latest version of Python 3, run the command below.

      If you already have the latest Python installed, you will see something like the message below.

      3) Run python3 --version to check if Python 3 is installed.

      If you install Python 3.7.X, you can also check its version using this command:
