I use Scribus 1.5.6. How can I use Python 3 (build in)? I installed the last version of Python 3. How can I use it?
My suggestion is to next release (1.6 maybe). The user could set internal Python 3 or set a external path (e.g. C:\Python3; /lib/python3...).
This alternative could be good because you did not need a new release for new Python releases (by security patch, for example). The user (as me) can update Python from their page and ready.
