Which goes really nicely into the next question.
It seems the default right now is 2.7:
$ python --version
Will this automagically change on Jan 1, 2020?
$ python3 --version
The python people recommended keeping python for python 2, and using
python 3. Unfortunately, at least one prominent python package, anaconda,
python for python 3.
Is there a way to get it changed now and see what is in trouble
there is very little python that I know I am using).
has lots of useful
Python packages that are actively maintained are being converted to use
python 3. In many cases this can be done in a way that allows the code
to use either python 2 or python3. The problem comes with older,
packages. Often these are orphaned because there is something better
you should be using, for some definition of "better". The major reason for
python 3 was to better support unicode, so linux distributions with
global reach needed python 3.
There has been a global shift in the importance of Chinese, Korean, and
Japanese (CJK) language customers to Western vendors. Python 3 is
one consequence, but we also have lualatex and unicode fonts in place
of Postscript. Western companies selling in CJK markets need unicode
for web sites, manuals, and the software they distribute.
A while ago I compared lists of python 2 and python 3 packages for
Ubuntu. The python 2 list was much longer, but there were only a
few python 2 packages installed that did not have python 3 versions.
You might find a similar exercise useful for Fedora.
