python.org has shipped faulty distributions before, sadly. Best to make sure your lesson plan works on each Python version someone might use, on every OS, etc. Or just use a common configuration.

Also, are you abandoning Mac users?

I'm just a viewer of that course. I guess for Mac users, it's easy, cause MacOS already comes with Python (3.x?) preinstalled. The course author himself video streams from the MacOS system.

MacOS has only had Python 2.x installed. Python and Ruby have both been deprecated in Catalina (10.15) and will not be pre-installed on MacOS in future releases:

https://developer.apple.com/documentation/macos_release_note...

> Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won’t include scripting language runtimes by default, and might require you to install additional packages. If your software depends on scripting languages, it’s recommended that you bundle the runtime within the app.

I use a Mac, it's true -- but I also have plenty of people using Windows and Linux in the course. I try to help everyone to get it installed on their systems.

Also: The Mac comes with Python 2. I'm using Python 3, and hope that everyone will indeed install it!
