Detecting ArcGIS Pro version using ArcPy

Question

Is there a Pythonic way (e.g. arcpy, os) to detect which version of ArcGIS Pro is installed on a machine (e.g. 2.8.1 vs 2.8.2)?

I found a similar question for ArcPy in ArcMap (Detecting format/version of ArcMap toolbox using ArcPy), but am curious if Esri added the functionality. So far, I've looked in arcpy.Describe and os.environ

Answer 1

You can use:

arcpy.GetInstallInfo()['Version']

Strip the ['version'] and you'll get back the entire dictionary of ArcGIS Pro info.

Answer 2

I very much prefer @KHibma's answer, but it seems os.environ does indeed provide a clue, but not the full story:

import arcpy
import os
environ_details = os.environ
print(environ_details["ESRIACTIVEINSTALLATION"])
### conversely...
print(arcpy.GetInstallInfo()['Version'])

The above prints:

ArcGISPro2.8
2.8.1
