pandas.DataFrame.iloc — pandas 0.18.1 documentation (original) (raw)

DataFrame.iloc¶

Purely integer-location based indexing for selection by position.

.iloc[] is primarily integer position based (from 0 tolength-1 of the axis), but may also be used with a boolean array.

Allowed inputs are:

• An integer, e.g. 5.
• A list or array of integers, e.g. [4, 3, 0].
• A slice object with ints, e.g. 1:7.
• A boolean array.
• A callable function with one argument (the calling Series, DataFrame or Panel) and that returns valid output for indexing (one of the above)

.iloc will raise IndexError if a requested indexer is out-of-bounds, except slice indexers which allow out-of-bounds indexing (this conforms with python/numpy slice semantics).
