Okey. I manged to get this far:

dpkg --status $(dpkg --get-selections | cut -f1) | grep "^Depends" |grep python

Problem is that it surely lists only python dependencies but in the same time it doesn´t show the original package name :| So how I can make list so that it also shows the original package name. Any testers around here to teach me

Reason for all this is that I´m starting to believe that python should be avoided for processes running constantly, like Eero said in bugzilla:
https://bugs.maemo.org/show_bug.cgi?id=8723#c93

"...Using things like Python for always running processes is a really bad idea...."
