Python 3 does not seem to be installed by default on MacOS, but yesterday I 
had no trouble installing Annaconda3 and running Leo.

Btw, Qt on MacOS does support --gui=qttabs, so there seems to be no reason 
not to have --gui=qt be a synonym for --gui=qttabs.

You are probably right.  I was not successful in running Leo with the 
python3 which came with Ubuntu, but that was because there was no matching 
pyQt5 package available at the time when I tried.
I installed python3 and pyQt5 with conda, and that worked for me. This may 
no longer be an issue, depending on the library versions available now. 
I'll find out soon when I try a clean install in the next two weeks.

In my original post I was just thinking about some people, who may not even 
try Leo, because they fail to be able to install it on the first try, but 
most potential Leo users have probably enough computer skills to cope.

Not sure about that, my
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"
is running 2.7 by default, and I'm sure I did a fresh install, not an
upgrade.  99.5% sure anyway ;-)

But I do think Python 3 is *installed* by default on 18.04.  3.6.7
currently.

Cheers -Terry

Correction:

as far as I heard, Python 3 is already the default on the currrent Ubuntu 
18.04 LTS. I was under the wrong assumption that Python 2 is the default, 
because when I upgraded from 16.04 LTS to 18.04 LTS the default Python 
installation did not change from 2 to 3.

Sorry, if I caused any confusion.

That makes me wonder what Apple is doing. Does anyone know what the default 
Python version is for new MacOS installations? Mine is several years old 
and Python 2.x. I keep the OS updated, but don't think that includes Python 
updates by default (at least I don't think so).

Most of my work is on Windows and I can update Python easily enough myself. 
Not so much with my MacBook Pro for traveling.

Leo 5.9 will run on Python 2.

I'll let the Ubuntu folks figure out how to transition to Python 3.

Re: No python 2 work after December 1, 2019

[Josef]

Hmm,

I think the default installation of Leo should always run on Ubuntu LTS.

Ubuntu LTS and derivatives still have by default Python 2 installed. The 
next Ubuntu LTS won't be out until April 2020 (and the automatic upgrade 
from an earlier LTS won't happen until Ubuntu 20.4.1, probably around June 
2020).
