May I suggest you to fix this. I am going through this training "Get started with Python in ArcGIS Pro" in the Tutorials in the Learn ArcGIS or Tutoral Gallery| Documentation section.
What I found is a missing is that it is diffcult to know which version the IDLE is... Let me show you
No mention of which version IDLE it is ? The grey above the menu shows none mention which version it is.


So maybe fix this is to help out the new learners about the IDLE module.
