Prior to installing ArcGIS Pro 1.3 (I am now at 1.3.1), on Windows 7 SP1, I have been starting IDLE in a Python Shell Window from the Windows Start Menu using IDLE (Python GUI) in the Python 3.4 folder. I can still do that but it reports that I am using Python 3.4.3.
However, when I use Windows Explorer and right-click a *.py file and choose Edit with IDLE (ArcGIS Pro) the Python Script Window that opens reports that I am using Python 3.4.4.
In the help for Python in ArcGIS Pro 1.3 it says:
In prior versions of ArcGIS Pro, Python was accessed outside of ArcGIS
Pro through a separate installation of Python for ArcGIS Pro. Starting
in ArcGIS Pro 1.3, Python for ArcGIS Pro is no longer required and
should be uninstalled to avoid confusion.
which makes me suspect that I should no longer be using or have the Python 3.4 folder under All Programs on the Windows Start Menu.
If I were to delete it, then how would I start the Python Shell Window of IDLE with Python 3.4.4?

You can start the Python IDLE GUI from the Start Menu using the ArcGIS Pro Python command prompt.
This will open a command prompt window at the current ArcGIS Pro python conda environment. Typing
idleat this prompt will open the IDLE GUI.
