blah blah here's the fix' or hell even a response would be greatly appreciated.

Anyway if I could get the appropriate 'syntax' OR even be told 'thats not the issue. I tried to look it up but the nomenclature stated on the forums is just irritating and just too much for me. As it says 'syntax error' when my gunga brain attempts to just throw the file inside python. I also looked online how to make it default(python 3) and was told not to becuase 'blah blah some files er something will crash because it needs blah blah python 2.7.10 or whatever the frick.'(In my mind of course) So I know to get into to python 3 but I have no idea how execute THE file. Now, I have it installed however I dont know how to run it in 3.8 as the default python is in python 2.7.10. No idea what to do in regards to coding, but I believe I need to have it run in python 3.8.
