For indexing, the counting isn’t starting from 0, (0,1,2,3…) instead it it starting from 1, (1,2,3,4…)

Normal counting (positive indexing) is counted from left to right, but Negative indexing it counted from right to left.

Also, in such “Indexing”, the final number has one number subtracted at the end, meaning if it’s (list[-4:-1]) here it would end at -2 not -1.
