Although Lua has the advantage of  being used in darktable (there are
potentially some scripts that could be re-used), one cannot deny that
the community involvement of python is quite big compared to lua. At
least it's not a lisp like language, that has never really become
mainstream. That would not get my vote, but I'm on the fence of Lua vs.
Python.

Perhaps some measure is to look at usage of languages in github repos. 
In 2018 python was 2nd with nearly 15% (javascript 1st with 23%).  Lua 
19th with 0.7%   Only perl is below Lua . You can find the report here:
