Feeling brave? Don't mind reporting bugs? Enjoy giving feedback? Then we'd love you to take a sneak peak at the (unfinished work in progress) next version of Mu. These are unsigned installers:
If you're using Mu at EuroPython's beginners' day, this is the version you should install.
There are many ways to install Mu. The simplest is to download the officialinstaller for Windows or Mac OSX. If you find you cannot install Mu because thecomputer you are using is locked down, you should try out PortaMu: a method ofrunning Mu from a pendrive on Windows or OSX. You can also usePython’s built-in pip tool. Some Linux distributions come with Mu packagedalready (and you should use your OS’s package manager to install it). Finally,if you’re on Raspbian (the version of Linux for Raspberry Pi) you can installMu as a package.
If you’re a developer, you can find the source codeon GitHub.
When the download is complete, your Mac automatically opens the disk image for you. The disk image actually looks like a folder. Inside this folder, you see a number of files, including python.mpkg. The python.mpkg file is the one that contains the Python application. The text files contain information about the build, licensing, and any late. Pyzo is a free and open-source computing environment based on Python. If you're used to e.g. Matlab, Pyzo can be considered a free alternative. Pyzo is a Python IDE that works with any Python interpreter installed on your system, including Conda environments. The IDE is aimed at interactivity and simplicity, and consists of an editor, a shell. Python is a free, open-source interpreted language that stands out for its versatility in supporting several programming paradigms, whether utilizing object-oriented language. In this tutorial we’ll be using py2app to create a standalone OSX application from a Python 2 or 3 source code with a simple Tkinter user interface. 'py2app is a Python setuptools command which will allow you to make standalone application bundles and plugins from Python scripts. Py2app is similar in purpose and design to py2exe for Windows.' Relevant links about py2app: Documentation Source. Python is a free, open-source interpreted language that stands out for its versatility in supporting several programming paradigms, whether utilizing object-oriented language or imperative syntax, or using its command line to work in a functional way, as with languages like Haskell.
On Linux, in order for Mu to work with the MicroPython based devices you need to ensure you add yourself to the correct permissions group (usually the dialout or uucp groups). Also make sure that your distribution automatically mounts flash devices, or make sure to mount them manually.

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.
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. Android software download for windows 10.
If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.
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:
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.
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.
With Python 3.9, you can use either python or pythonw.
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.
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.
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/.
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.
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.
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.
The MacPython mailing list is an excellent support resource for Python users anddevelopers on the Mac:
