Or, another words, ideally we want all these to work:
python2 /usr/bin/django-admin - python2
python3 /usr/bin/django-admin - python3
/usr/bin/django-admin - autodetect.
One possibility is to write a shell script that is also valid Python
code. PoC:
#!/bin/sh
sh=''''
if command -v python3 > /dev/null; then
exec python3 "$0" "$@"
else
exec python "$0" "$@"
fi
' '''
import sys
print("I'm Python %d.%d!" % sys.version_info[:2])
Another possibility is to create the django-admin symlink in maintainer
scripts, with the target depending on which of python*-django packages
are installer. This is how src:sphinx manages its /usr/bin/sphinx-*
symlinks.
