That’s not the case for your Python programs.

The GPL license has some problems related to the fact that all software derived from GPL software must be released as GPL as well, and the source code of the software must be distributed to anyone that wants access to it. This license is GPL-compatible, which means you can combine Python with software that is GPL, Python itself is not GPL. Python is open source, and released with the Python Software Foundation License Version 2. Zope Corporation is a sponsoring member of the PSF. In 2001, the Python Software Foundation (PSF, see ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. In October of the same year, the PythonLabs team moved to Digital Creations (now Zope Corporation, see ). In May 2000, Guido and the Python core development team moved to to form the BeOpen PythonLabs team.
In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see ) in Reston, Virginia where he released several versions of the software. Guido remains Python’s principal author, although it includes many contributions from others. Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum (CWI, see ) in the Netherlands as a successor of a language called ABC. A new panel will appear with an interesting recap on the history of Python and its governance:

Get python for mac install#
One option is to use Homebrew to install the latest Python release.Īnother option is to use the official Python packages and that’s the approach we’ll follow. In my case I had Python 3.8, but Python 3.9 was available to be installed. However you have little control over the version number you run, as Apple updates it only with new Xcode releases. Python 3 is the one we’re going to use for modern Python development. In this case you can run python3 on your terminal to check the exact version installed, and if it’s recent enough you might be already set up. If you install Xcode, the Apple Development IDE, it installs Python 3 in /usr/bin/python3. Change the URL if necessary.MacOS installs Python 2 (outdated) by default, for compatibility reasons, making it available as /usr/bin/python. Please note that python3.rb was renamed to python.rb at some point. There is also: where you can install using brew install sashkab/python/python34 and brew link python34 -force Now you can use brew install with the corresponding commit hash: if you want to install a specific version then, you must check before install. This is another package manager but based and mainly meant for python, it also gives the equivalent of python's virtual environments and pyenv (as per other answer) and so each project can be in a different python and different libraries (Macports only switches python version for all projects) The issue with Homebrew is that it assumes that things in /usr/local are installed by it and so brew doctor will report these pythons and libraries as issues and as this question shows also the frameworks in /Library will be problematic.ĮDIT 8/2018 *** I would now suggest using conda either miniconda or anaconda. The other way is install direct from This will install a python into /usr/local/bin I think this installs a python and python3 executable. e,g, to select macports python 2.7 port select -set python python27Įach package manager needs to run as the only package manager otherwise it will be confused with unexpected different versions of libraries and executables on its paths.įrom comments the similar homebrew way is given in Short answer seems to be brew switch the equivalent to port_select Python version managers For example to install 3.4 do sudo port install python34 There is also a python_select port that running it allows you to choose which version of python is run by /opt/bin/python. There are separate ports for several python versions 2.x and 3.x currently 2.4, 2.5, 2.6, 2.7 and 3.1, 3.2, 3.3 3.4 and 3.5. The first is using Macports as the package manager.
I have done this sort of thing in two ways - however both do not coexist with homebrew although I suspect there should be a way similar to the macports one.
