I'm currently running ArcMap basis 10.2.0. in the pervious version 10.1 I was able to download an external module that could run python code. In that module you were able to show line numbers which greatly help when you are learning coding. It was locate on C:\Python27\ArcGIS10.1\lib\site-packages. It was an .exe and the desk top module was a snake. I can't seem to find it when I go to C:\Python27\ArcGIS10.1\lib\site-packages. does anyone know if it is still available if yes how to download it. Thanks, chris
