pandas.Index.take#
- Index.take(indices, axis=0, allow_fill=True, fill_value=None, **kwargs)[source]#
Return a new Index of the values selected by the indices.
For internal compatibility with numpy arrays.
- Parameters:
- indicesarray-like
Indices to be taken.
- axisint, optional
The axis over which to select values, always 0.
- allow_fillbool, default True
How to handle negative values in indices.
False: negative values in indices indicate positional indices from the right (the default). This is similar to
numpy.take().True: negative values in indices indicate missing values. These values are set to fill_value. Any other negative values raise a
ValueError.
- fill_valuescalar, default None
If allow_fill=True and fill_value is not None, indices specified by -1 are regarded as NA. If Index doesn’t hold NA, raise ValueError.
- **kwargs
Required for compatibility with numpy.
- Returns:
- Index
An index formed of elements at the given indices. Will be the same type as self, except for RangeIndex.

Examples
>>> idx = pd.Index(["a", "b", "c"]) >>> idx.take([2, 2, 1, 2]) Index(['c', 'c', 'b', 'c'], dtype='str')
