# pandas.Index.all

Index.all(*args, **kwargs)

  Return whether all elements are Truthy.

  This is equivalent to calling `bool(self.all())`. An empty Index will return True.

  Parameters:
    *args

      Required for compatibility with numpy.

    **kwargs

      Required for compatibility with numpy.

  Returns:
    bool or array-like (if axis is specified)

      A single element array-like may be converted to bool.

  See also

  `Index.any`

    Return whether any element in an Index is True.

  `Series.any`

    Return whether any element in a Series is True.

  `Series.all`

    Return whether all elements in a Series are True.

  Notes

  Not a Number (NaN), positive infinity and negative infinity evaluate to True because these are not equal to zero.

  Examples

  True, because nonzero integers are considered True.

      >>> pd.Index([1, 2, 3]).all()
      True

  False, because `0` is considered False.

      >>> pd.Index([0, 1, 2]).all()
      False
