Your comment is too ambiguous for me to comprehend... Are you referring to the case where devs keep python modules and scripts in /many/ places on their disc, or something else?

I'll check it out. If the path can be trimmed there, then the problem is solved for me, but what about everyone else?

If i do i will post it. First i need to respond to someone who always needs me to explain every detail because he has trouble comprehending even the simplest of ideas. *cough*even*cough*prano

IDLE already has a build in command from the context menu called "go to file/line" that will parse any right-clicked line for file paths and line numbers, then, open that file in a new IDLE editor instance and adjust the view so you can see the lineno in question (typical IDE stuff)... but most devs prefer to use IDEs with less bugs asinine interfaces :-)
