How to go to the end of an array
arrays, python
Solution
Indexes start from 0.
l = [3, 5, 7]
# 0 1 2
The last item is at index `len(l) - 1`, not `len(l)`.
Also, use
j = x[-1]
since negative indexes count from the end of the list.
Problem
To go the the last value in an array, would you use the code: ``` j = x[len(x)-1] ``` because this seems to be giving me the last but one, so this is really a question of how the len() thing works with arrays.
