I believe that the [i] notation is to indicate that it has to be a valid
index to your list. If i isn't a valid index, you get an IndexError.
>>> spam=['this', 'is', 'a', 'list']
>>> spam.pop(1)
'is'
>>> spam.pop(4)
Traceback (most recent call last):
File "<pyshell#10>", line 1, in -toplevel-
spam.pop(4)
IndexError: pop index out of range
