Code Snippet: script code based on EPM environment

We may have some scripts which code differs from one environment to another. Maintaining different code for same script is a risky task.
What about having one single script which you can migrate into the other environments with no risks?
How can I make my code dynamic based on the EPM environment I'm working with?
Let's have a look!

Getting EPM environment based on FDMEE Server hostname

 Snippet:       Get environment running the script based on the FDMEE Server
                hostname

 Notes:         This snippet can be pasted in any event/custom/import script.
                Output will be logged in the FDMEE process log 
                (...\outbox\logs\)
                
                This script uses socket python module
                
 Instructions:  Set log level (global or application settings) to 5 
                To add new servers, include an entry in the dictionary.
                You can get hostnames by executing command "hostname"
                from the command line in the FDMEE server(s).
 
 Hints:         Use this snippet to avoid having different script codes
                across environments. The right code will be executed
                at runtime based on the FDMEE server running the process
               
 FDMEE Version: 11.1.2.3 and later
