In python, how do I get the result

$[\text{'}$RIVER$\text{'},\text{'}$f$\text{'}]$

From x $=["$a$","$b$","$c$",$ "RIVER", $"$e$","$f$"]$ how do you so much about Python? You know a lot, but the answer is still not quite right. This is not a homework question or anything. I am just trying to learn. So$,$ basically, it is very difficult to obtain certain results with that last index number? Well this is what my output was using your method $\{\text{'}$F$\text{'},$ 'RIVER'$\}.$ You came the closest between chatgpt and bard. I refuse to call him G$.$ If this was a homework assignment, I would have gotten a zero. But, you get a thumbs up because you were so close. Thanks anyway!!! I figured it out x$[3$:$6$:$2].$
