Line numbers were added to the IDLE editor two days ago and will appear in the upcoming 3 8 0a3 and later 3 7 5   For new windows  they are off by default  but this can be reversed on the Setting dialog  General tab  Editor section   For existing windows  there is a new Show  Hide  Line Numbers entry on the Options menu   There is currently no hotkey   One can select a line or bloc of lines by clicking on a line or clicking and dragging   Some people may have missed Edit   Go to Line   The right-click context menu Goto File Line works on grep  Find in Files  output as well as on trackbacks

If you are trying to track down which line caused an error  if you right-click in the Python shell where the line error is displayed it will come up with a  Go to file line   which takes you directly to the line in question
