run my script in a spefic version or any later one

[Skaperen]

if you have a system with 3.5 as the standard (such as Ubuntu 16.04 LTS) and have installed 3.8 from source then that symlink would still point to 3.5 in which case my script needs to use 3.8 (3.5 does not support f-strings). i don't know if changing the symlink would still work for the system scripts. some are in Python. if they work in 3.5 i'd think they'd work in 3.8 but i can't be 100% confident.
