# numpy.char.compare_chararrays

char.compare_chararrays(a1, a2, cmp, rstrip)

  Performs element-wise comparison of two string arrays using the comparison operator specified by cmp_op.

  Parameters:
    a1, a2 array_like

      Arrays to be compared.

    cmp{“<”, “<=”, “==”, “>=”, “>”, “!=”}

      Type of comparison.

    rstrip Boolean

      If True, the spaces at the end of Strings are removed before the comparison.

  Returns:
    out ndarray

      The output array of type Boolean with the same shape as a and b.

  Raises:
    ValueError

      If cmp_op is not valid.

    TypeError

      If at least one of a or b is a non-string array

  Examples

      >>> a = np.array(["a", "b", "cde"])
      >>> b = np.array(["a", "a", "dec"])
      >>> np.compare_chararrays(a, b, ">", True)
      array([False,  True, False])
