# pandas.core.groupby.DataFrameGroupBy.take

property DataFrameGroupBy.take

  Return the elements in the given positional indices along an axis.

  This means that we are not indexing according to actual values in the index attribute of the object. We are indexing according to the actual position of the element in the object.

  Parameters
    indices array-like

      An array of ints indicating which positions to take.

    axis{0 or ‘index’, 1 or ‘columns’, None}, default 0

      The axis on which to select elements. `0` means that we are selecting rows, `1` means that we are selecting columns.

    is_copy bool

      Before pandas 1.0, `is_copy=False` can be specified to ensure that the return value is an actual copy. Starting with pandas 1.0, `take` always returns a copy, and the keyword is therefore deprecated.

      Deprecated since version 1.0.0.

    **kwargs

      For compatibility with `numpy.take()`. Has no effect on the output.

  Returns
    taken same type as caller

      An array-like containing the elements taken from the object.

  Examples

      >>> df = pd.DataFrame([('falcon', 'bird', 389.0),
      ...                    ('parrot', 'bird', 24.0),
      ...                    ('lion', 'mammal', 80.5),
      ...                    ('monkey', 'mammal', np.nan)],
      ...                   columns=['name', 'class', 'max_speed'],
      ...                   index=[0, 2, 3, 1])
      >>> df
           name   class  max_speed
      0  falcon    bird      389.0
      2  parrot    bird       24.0
      3    lion  mammal       80.5
      1  monkey  mammal        NaN

  Take elements at positions 0 and 3 along the axis 0 (default).

  Note how the actual indices selected (0 and 1) do not correspond to our selected indices 0 and 3. That’s because we are selecting the 0th and 3rd rows, not rows whose indices equal 0 and 3.

      >>> df.take([0, 3])
           name   class  max_speed
      0  falcon    bird      389.0
      1  monkey  mammal        NaN

  Take elements at indices 1 and 2 along the axis 1 (column selection).

      >>> df.take([1, 2], axis=1)
          class  max_speed
      0    bird      389.0
      2    bird       24.0
      3  mammal       80.5
      1  mammal        NaN

  We may take elements using negative integers for positive indices, starting from the end of the object, just like with Python lists.

      >>> df.take([-1, -2])
           name   class  max_speed
      1  monkey  mammal        NaN
      3    lion  mammal       80.5
