There s a set of useful extensions to IDLE called IDLEX that works with MacOS and Windows http   idlex sourceforge net   It includes line numbering and I find it quite handy  amp  free    Otherwise there are a bunch of other IDEs some of which are free   https   wiki python org moin IntegratedDevelopmentEnvironments

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

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

Version 3 8 or newer  To show line numbers in the current window  go to Options and click Show Line Numbers  To show them automatically  go to Options  gt  Configure IDLE  gt  General and check the Show line numbers in new windows box  Version 3 7 or older  Unfortunately there is not an option to display line numbers in IDLE although there is an enhancement request open for this  However  there are a couple of ways to work around this   Under the edit menu there is a go to line option  there is a default shortcut of Alt G for this    There is a display at the bottom right which tells you your current line number   position on the line
