Control: clone -1 -2
Control: reassign -1 python-defaults
Control: retitle -1 please set python and python-minimal's priority to optional so it's not installed in the standard task
Control: reassign -2 python2.7
Control: retitle -2 please set python2.7's priority to optional so it's not installed in the standard task

Hello,

Priority: standard is exactly what defines what will be installed when
you select the "standard" task in tasksel. All of python-minimal,
python2.7, and python have Priority: standard.

So this is to be changed in the python-defaults and python2.7 packages.
(and possibly set the python3 equivalents' priority to standard
instead).
