Zachary Ware <[email protected]> added the comment:
`-1` is not out of bounds unless the array is empty; negative indices count
from the other end:
>>> a = list("some array")
>>> a
['s', 'o', 'm', 'e', ' ', 'a', 'r', 'r', 'a', 'y']
>>> a[-1]
'y'
>>> b = []
>>> b[-1]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: list index out of range
See about halfway down this [1] section; look for "Indices may also be
negative".
