I recommend having a shell alias to execute python3 each time you run python.Last Updated: Wednesday 29 th December 2021 Remember to not be confused by having the python command on your system that points to the old Python 2. Then we have a link to the official documentation, the license, and Python Launcher, an utility that lets you to locate and manage different Python versions installed on the system, and instruct scripts to use a specific version. The other files contained in that folder are IDLE, an application that opens the Python interpreter in its own window:

This is because Python includes its own private copy of OpenSSL 1.1.1, and we need to install a curated bundle of default root certificates from the third-party certifi package.Ĭertifi provides Mozilla’s carefully curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hostsĭouble-click on Install Certificates to run it, and it will to its job quickly: You will now also find a new folder under “/Applications/Python 3.9” (change that with your exact version number), with some files:Īs the instructions said in the last installation panel, you need to run the “Install mand” to install the SSL certificates needed by Python. Running python3 in the macOS terminal opens the Python 3.9 interpreter we just installed: If you have Xcode installed, this will overwrite the old version that Xcode installed. When it’s finally installed, Python is installed as /usr/bin/python3 You can release the source if you want, but it’s not required. 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:

Go to, choose the Downloads menu, hover “Mac OS X” and a panel with a link to download the official package will appear:

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. MacOS installs Python 2 (outdated) by default, for compatibility reasons, making it available as /usr/bin/python.
