Don -
I think I need a good tutorial on Linux Ubuntu and one on Python .
Preferably free but if there is a particularly
good book or online course I could maybe pay if its not too expensive .
IMHO, for learning Unix (including Linux) you should first learn the
bash shell. e.g. with "Learning the bash Shell" O'Reilly or one of the
thousands online resources. Open a terminal emulator and there you
are.
bash resembles a bit the good old DOS terminal, but very soon you will
realize it's power.
