Can we make sextractor++ python 3 only?

Investing any effort on python 2 may not be very productive, considering it will be EOL by the end of the year. Supporting both could be confusing for the users that try to compile.

I'm all for getting rid of Python 2 but how will it work for people still using a distribution with Python 2 as default? Also we need to be sure that we fulfill the Euclid requirements.

So we need to be careful and check that if we want to switch to Python 3 only.
