How to run Splunk using python 3.7

[pbankar]

I'm developing a Technology AddOn (TA) using Modular Input and as per the latest Splunk norms they will be deprecating python 2.7. I'm using Splunk 8.

I'm making changes in the TA as per the Splunk Platform Upgrade Readiness App and need to know how do I test my TA if its running using python 3.7 or not.

On the command line, I'm getting this output:

When you upgrade to version 8.0, Splunk Enterprise will continue to use the Python 2 interpreter globally by default, but Splunk Web will support only Python 3.7.

You can change python version by configuring server.conf .

Splunk Enterprise version 8.0 include a global setting, python.version, to specify which Python interpreter to use across an instance. The global setting resides in the server.conf file, located in $SPLUNK_HOME/etc/system/local/. The stanza that controls Python version is [general]

python.version is set to python2 by default in Splunk Enterprise version 8.0. To specify Python 3, set python.version = python3. These settings specify the interpreter to use if a script-level setting has not been specified, but script-level settings take precedence over the global setting, except if Python 3 is forced. 

Check Python interpreter settings in below links.
