Python IDE Configuration with ArcGIS Pro 1.3

In previous versions of ArcGIS Pro, 1.2 and earlier, to use arcpy, the ArcGIS module for Python, in external scripts, you had to perform a secondary installation. A really handy feature of ArcGIS Pro is autoupdating. When prompted to update Pro from version 1.2 to 1.3, I happily said yes.

Unfortunately, after upgrading I discovered my Python IDE of choice, PyCharm, no longer knew where to find the Python executable. Fortunately I have the luxury of being able to dig up the right person at Esri to tell me how to fix this.

Although there is still a Python34 directory in the C:\ drive, you will not find python.exe in here. Rather, you need to configure your IDE to find the executable at C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\python.exe.
