  Form the intersection of two Index objects.

  This returns a new Index with elements common to the index and other.

  Parameters:
    other Index or array-like

      An Index or an array-like object containing elements to form the intersection with the original Index.

    sort True, False or None, default False

      Whether to sort the resulting index.

      - None : sort the result, except when self and other are equal or when the values cannot be compared.

      - False : do not sort the result.

      >>> idx1.intersection(idx2)
      Index([3, 4], dtype='int64')
