This LSB scripts were made in python2.7 and adapted for python3( for what it seems.. )
I assume they are in pretty much any distro out there..
I agree with fsmithred, they are, some sort of... a "black-magic" art

I don't know who is a "python guy",

Long Story Short:
I stated that I couldn't help, because I am not a Python programmer..
