Reading this ESRI support information from the Internet (select English language at the bottom of the page, other translations aren't always updated), it's not clear to me if a 10.7.x version of ArcGIS Server always comes with both 2.7 and 3.6 versions of Python language, or may sometimes come with the 2.7version only.

Is an ArcGIS Server component the same whether it is linked to an ArcGIS Desktop installation or an ArcGIS Pro one?

1 Answer 1


From the linked article (emphasis mine):

The ArcGIS Server component of ArcGIS Enterprise also ships with Python. In recent releases, both Python 2.x and Python 3.x runtimes are provided.

Below that, it is specified that versions 10.6 and higher come with Python 3.6.x and 2.7.x. I see no indication that 3.6 is not included in any 10.7 version.

ArcGIS Server is in no way 'linked' to either ArcGIS Desktop or ArcGIS Pro (it's a separate installation), so the answer to the second part of your question would be Yes.

  • Technically, if you install Desktop first, and then the 64-bit Background Geoprocessing extension, if you then install Server, it will skip installation of 64-bit 2.7.x Python, so there is a tenuous linkage, but not in the meaning of the OP.

  • Note that the ArcGIS Server's 3.x version of Python will be sort of "buried" deep in the install directory. You don't see it get dropped down at the typical C:\PythonXX path when installing ArcMap (Python 2.7)
