Thanks for the encouragement! Glad you liked it! It's one of my first Hive-related scripts, so I was kind of anxious letting it out of the gates. (I'm kind of slow releasing these, lol, but I might get faster in time.)

I'm currently rewriting parts of the script, because after testing it for a while I noticed it needs better error handling, especially in situations where the servers act up. But from the command line it usually works best, because in case of error, one can always run it again.

About that nargs='?', it just lets the script continue with no arguments, basically it falls back to using the default variable set for account_name.
