# pandas.Index.shape

`Index.``shape`

  Tuple of array dimensions.

  Notes

  May be used to “reshape” the array, as long as this would not require a change in the total number of elements

  Examples

      >>> x = np.array([1, 2, 3, 4])
      >>> x.shape
      (4,)
      >>> y = np.zeros((2, 3, 4))
      >>> y.shape
      (2, 3, 4)
      >>> y.shape = (3, 8)
      >>> y
      array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
             [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
             [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])
      >>> y.shape = (3, 6)
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
      ValueError: total size of new array must be unchanged
