In Catalina 10.15.4, from Terminal, python2 -version returns Python 2.7.16 python3 -version returns Python 3.7.3 which python or python -version tells what version is used by default. To use python3 instead of python2, I added an alias echo 'alias python='python3' /.zshrc. Using Python on a Macintosh¶ Author. Bob Savage Python on a Macintosh running Mac OS X is in principle very similar to Python on any other Unix platform, but there are a number of additional features such as the IDE and the Package Manager that are worth pointing out.

(This is a reminder to myself, and maybe a help for someone else who might be in the same situation as me. The purpose was to be able to lint documentation I’m trying to update for the pip project work.)

$ xcrun python3 Python 3.7.3 (default, Sep 5 2019, 17:14:41) Clang 11.0.0 (clang-1100.0.33.8) on darwin. However, I notice you mention that you are using IDLE from Python 3.7.3. If so, be aware that that is not the latest release of either Python 3 or Python 3.7 (3.7.3 predates Catalina.) 3.7.7 is the most recent for 3.7 but Python 3.8 is now current and its most recent release, 3.8.3, has the most up-to-date support for 10.15.

This applies to installing “the latest” Python on Mac OS X 10.15.6.

I’ve used this helpful How-TO. Everything worked until the very end where brew couldn’t create a necessary directory:

(no idea why!)

I reran install python and got:

Solution (hack?)

The solution was to create the /usr/local/Framworks directory manually:

Then change the owner and group to mirror other directories (bernard:admin)

And finally run the brew link command from above:

And then I could start what I wanted to actually do. 🙂

Release Date: Aug. 17, 2020

Python 3.7.9 was a security release of Python 3.7.

There are now newer security releases of Python 3.7 that supersede 3.7.9 and Python 3.9 is now the latest feature release of Python 3. Get the latest releases of 3.7.x and 3.9.x here.Python 3.7.8 was the last bugfix release of Python 3.7 before 3.7 entered the security-fix phase of its life cycle. We plan to provide security fixes until mid 2023, five years after its initial release. Note that there are updated binary installers available for 3.7.9.

Binary installers are normally not provided for security fix releases. However, since 3.7.8 was the last 3.7.x bugfix release and there are security fixes published in 3.7.9 that apply to users of some of the binary installers provided with 3.7.8, we have made an exception for 3.7.9 and are also updating the Windows and macOS binary installers. We do not plan to provide further binary updates for future 3.7.x security releases.
