.iloc() is primarily integer position based (from 0 to length-1 of the axis).
Allowed inputs are:
An integer, e.g. 5.
A list or array of integers, e.g. [4, 3, 0].
A boolean mask. E.g [ true, false, false ]
A string slice object with ints, e.g. "1:7"
Note: only the start label is included, and the end label is ignored. 
.iloc will raiseIndexError if a requested indexer is out-of-bounds.
