code to run in python3

[Skaperen]

Can I do this shorter or better ?

 if sys.version_info < (3,6): print("ERROR: This script needs Python 3.6 or later"); exit(99) 

my emphasis is on making it switch to the correct version.  do you think that is a bad idea?  or maybe it should anounce the switch?  or do you think it should just abort?

that tutorial was long and i could not read it all.  it started to get confusing as it seemed to be about packaging and installing.  and i could not figure out what the "wheel" thing was about.
